13 APPLICATIONS The AD862x is one of the smallest and most economical JFETs offered. It has true single-supply capability and has an input voltage range that extends below the negative rail, allowing the part to accommodate input signals below ground. The rail-to-rail output of the AD862x provides the maximum dynamic range in many applications. To provide a low offset, low noise, high impedance input stage, the AD862x uses n-channel JFETs The input common-mode voltage extends from.2 V below VS to 2 V below +VS. Driving the input of the amplifier, configured in unity gain buffer, closer than 2 V to the positive rail causes an increase in common-mode voltage error, as illustrated in Figure 5, and a loss of amplifier bandwidth. This loss of bandwidth causes the rounding of the output waveforms shown in Figure 39 and Figure 4, which have inputs that are V and V from +VS, respectively. VOLTAGE (2V/DIV) V SY =5V INPUT OUTPUT TIME (2µs/DIV) Figure 39. Unity Gain Follower Response to V to 4 V Step 323-B-38 The AD862x will not experience phase reversal with input signals close to the positive rail, as shown in Figure 29. For input voltages greater than +VSY, a resistor in series with the AD862x s noninverting input prevents phase reversal at the expense of greater input voltage noise. This current limiting resistor should also be used if there is a possibility of the input voltage exceeding the positive supply by more than 3 mv, or if an input voltage is applied to the AD862x when ±VSY =. Either of these conditions will damage the amplifier if the condition exists for more than seconds. A kω resistor allows the amplifier to withstand up to V of continuous overvoltage, while increasing the input voltage noise by a negligible amount.

14 The AD862x can safely withstand input voltages 5 V below VSY if the total voltage between the positive supply and the input terminal is less than 26 V. Figure 4 through Figure 43 show the AD862x in different configurations accommodating signals close to the negative rail. The amplifier input stage typically maintains picoamp-level input currents across that input voltage range. kω V mv 3mV kω +5V kω V SY = 5V kω +5V V SY = 5V, V V 2.5V VOLTAGE (mv/div) VOLTAGE (V/DIV) TIME (2µs/DIV) Figure 43.

Gain of Two Inverter Response to 2.5 V Step, Centered.25 V below Ground 323-B-4 The AD862x is designed for 6 nv/ Hz wideband input voltage noise and maintains low noise performance to low frequencies, as shown in Figure 35. This noise performance, along with the AD862x s low input current and current noise, means that the AD862x contributes negligible noise for applications with large source resistances. 6mV mv V 5V 6Ω The AD862x has a unique bipolar rail-to-rail output stage that swings within 5 mv of the rail when up to 2 ma of current is drawn. At larger loads, the drop-out voltage increases as shown in Figure 7 and Figure 8. The AD862x s wide bandwidth and fast slew rate allows it to be used with faster signals than previous single-supply JFETs. Figure 44 shows the response of AD862x, configured in unity gain, to a VIN of V p-p at 5 khz. The FPBW of the part is close to khz.

15 MINIMIZING INPUT CURRENT The AD862x is guaranteed to pa max input current with a ±3 V supply voltage at room temperature. Careful attention to how the amplifier is used will maintain or possibly better this performance. The amplifier s operating temperature should be kept as low as possible. Like other JFET input amplifiers, the AD862x s input current doubles for every C rise in junction temperature, as illustrated in Figure 8. On-chip power dissipation raises the device operating temperature, causing an increase in input current. Reducing supply voltage to cut power dissipation reduces the AD862x s input current. Heavy output loads can also increase chip temperature; maintaining a minimum load resistance of kω is recommended. The AD862x is designed for mounting on PC boards. Maintaining picoampere resolution in those environments requires a lot of care. Both the board and the amplifier s package have finite resistance. Voltage differences between the input pins and other pins as well as PC board metal traces may cause parasitic currents larger than the AD862x s input current, unless special precautions are taken. For proper board layout to ensure the best result, refer to the ADI website for proper layout seminar material. Two common methods of minimizing parasitic leakages that should be used are guarding of the input lines and maintaining adequate insulation resistance. Contaminants such as solder flux on the board s surface and the amplifier s package can greatly reduce the insulation resistance between the input pin and traces with supply or signal voltages. Both the package and the board must be kept clean and dry. PHOTODIODE PREAMPLIFIER APPLICATION The low input current and offset voltage levels of the AD862x, together with its low voltage noise, make this amplifier an excellent choice for preamplifiers used in sensitive photodiode applications. In a typical photovoltaic preamp circuit, shown in Figure 45, the output of the amplifier is equal to where: V OUT = ID(Rf) = R (P)Rf ID = photodiode signal current (A) Rp = photodiode sensitivity (A/W) Rf = value of the feedback resistor, in Ω P = light power incident to photodiode surface, in W The amplifier s input current, IB, contributes an output voltage error proportional to the value of the feedback resistor. The offset voltage error, VOS, causes a small current error due to the photodiode s finite shunt resistance, RD. p The resulting output voltage error, VE, is equal to R f VE = + VOS + Rf(I R D A shunt resistance on the order of MΩ is typical for a small photodiode. Resistance RD is a junction resistance that typically drops by a factor of two for every C rise in temperature. In the AD862x, both the offset voltage and drift are low, which helps minimize these errors. With IB values of pa and VOS of 5 mv, VE for Figure 45 is very negligible. Also, the circuit in Figure 45 results in an SNR value of 95 db for a signal bandwidth of 3 khz. PHOTODIODE R D MΩ I B C4 5pF I B V OS C F 5pF B R F.5MΩ ) AD8627 Figure 45. A Photodiode Model Showing DC Error OUTPUT OUTPUT AMPLIFIER FOR DIGITAL-TO-ANALOG CONVERTERS Many system designers use amplifiers as buffers on the output of amplifiers to increase the DAC s output driving capability. The high resolution current output DACs need high precision amplifiers on their output as current to voltage converters (I/V). Additionally, many DACs operate with a single supply of 5 V. In a single-supply application, selection of a suitable op amp may be more difficult because the output swing of the amplifier does not usually include the negative rail, in this case AGND. This can result in some degradation of the DAC s specified performance unless the application does not use codes near zero. The selected op amp needs to have very low offset voltage for a 4-bit DAC, the DAC LSB is 3 µv with a 5 V reference to eliminate the need for output offset trims. Input bias current should also be very low because the bias current multiplied by the DAC output impedance (about kω in some cases) adds to the zero code error. Rail-to-rail input and output performance is desired. For fast settling, the slew rate of the op amp should not impede the settling time of the DAC. Output impedance of the DAC is constant and code independent, but in order to minimize gain errors, the input impedance of the output amplifier should be as high as possible. The AD862x, with very high input impedance, IB of pa, and fast slew rate, is an ideal amplifier for these types of applications. A typical configuration with a popular DAC is shown in Figure 46. In these situations, the amplifier adds another time constant to the system, increasing the settling time of the output. The AD862x, with 5 MHz of BW, helps in achieving a faster effective settling time of the combined DAC and amplifier. 323-B-44 Rev. B Page 5 of

Unipolar Output AD8627 UNIPOLAR OUTPUT In applications with full 4-quadrant multiplying capability or a bipolar output swing, the circuit in Figure 47 can be used. In this circuit, the first and second amplifiers provide a total gain of 2, which increases the output voltage span to V.

Due to the very low bias current of the AD862x, high value resistors can be used to construct low frequency filters. The AD862x s picoamp-level input currents contribute minimal dc errors. Figure 49 shows an example, a Hz, 8-pole Sallen Key filter constructed using the AD862x. Different numbers of the AD862x can be used depending on the desired response, which is shown in Figure 48. The high value used for R minimizes interaction with signal source resistance. Pole placement in this version of the filter minimizes the Q associated with the lower pole section of the filter. This eliminates any peaking of the noise contribution of resistors in the preceding sections, minimizing the inherent output voltage noise of the filter.
