Output voltage swing extends to within mv of each rail providing the maximum output dynamic range. Offset voltage of 8 µv max, offset voltage drift of µv/ C, typ input bias currents below pa and low input voltage noise provide dc precision with source impedances up to a Gigaohm..8 MHz unity gain bandwidth, 9 db THD at khz and V/µs slew rate are provided for a low supply current of 8 µa.

13 AD8 APPLICATION NOTES INPUT CHARACTERISTICS In the AD8, n-channel JFETs are used to provide a low offset, low noise, high impedance input stage. Minimum input common-mode voltage extends from. V below V S to V less than. Driving the input voltage closer to the positive rail will cause a loss of amplifier bandwidth (as can be seen by comparing the large signal responses shown in Figures 8 and ) and increased common-mode voltage error as illustrated in Figure 9. The AD8 does not exhibit phase reversal for input voltages up to and including. Figure 8a shows the response of an AD8 voltage follower to a V to + V ( ) square wave input. The input and output are superimposed. The output polarity tracks the input polarity up to no phase reversal. The reduced bandwidth above a V input causes the rounding of the output wave form. For input voltages greater than, a resistor in series with the AD8 s plus input will prevent phase reversal, at the expense of greater input voltage noise. This is illustrated in Figure 8b. Since the input stage uses n-channel JFETs, input current during normal operation is negative; the current flows out from the input terminals. If the input voltage is driven more positive than. V, the input current will reverse direction as internal device junctions become forward biased. This is illustrated in Figure. GND (a) A current limiting resistor should be used in series with the input of the AD8 if there is a possibility of the input voltage exceeding the positive supply by more than mv, or if an input voltage will be applied to the AD8 when ± V S =. The amplifier will be damaged if left in that condition for more than seconds. A kω resistor allows the amplifier to withstand up to volts of continuous overvoltage, and increases the input voltage noise by a negligible amount. Input voltages less than V S are a completely different story. The amplifier can safely withstand input voltages volts below the minus supply voltage as long as the total voltage from the positive supply to the input terminal is less than volts. In addition, the input stage typically maintains picoamp level input currents across that input voltage range. The AD8 is designed for nv/ Hz wideband input voltage noise and maintains low noise performance to low frequencies (refer to Figure ). This noise performance, along with the AD8 s low input current and current noise means that the AD8 contributes negligible noise for applications with source resistances greater than kω and signal bandwidths greater than khz. This is illustrated in Figure 9. INPUT VOLTAGE NOISE V RMS k k k. k WHENEVER JOHNSON NOISE IS GREATER THAN AMPLIFIER NOISE, AMPLIFIER NOISE CAN BE CONSIDERED NEGLIGIBLE FOR APPLICATION.

(a) Response with R P = ; V IN from to Figure. (b) V IN = to + mv V OUT = to R P = 9.9 kω OUTPUT CHARACTERISTICS The AD8 s unique bipolar rail-to-rail output stage swings within mv of the minus supply and mv of the positive supply with no external resistive load. The AD8 s approximate output saturation resistance is Ω sourcing and Ω sinking. This can be used to estimate output saturation voltage when driving heavier current loads. For instance, when sourcing ma, the saturation voltage to the positive supply rail will be mv, when sinking ma, the saturation voltage to the minus rail will he mv. The amplifier s open-loop gain characteristic will change as a function of resistive load, as shown in Figures 9 through. For load resistances over kω, the AD8 s input error voltage is virtually unchanged until the output voltage is driven to 8 mv of either supply. If the AD8 s output is driven hard against the output saturation voltage, it will recover within µs of the input returning to the amplifier s linear operating region.

14 AD8 Direct capacitive load will interact with the amplifier s effective output impedance to form an additional pole in the amplifier s feedback loop, which can cause excessive peaking on the pulse response or loss of stability. Worst case is when the amplifier is used as a unity gain follower. Figure shows the AD8 s pulse response as a unity gain follower driving pf. This amount of overshoot indicates approximately degrees of phase margin the system is stable, but is nearing the edge. Configurations with less loop gain, and as a result less loop bandwidth, will be much less sensitive to capacitance load effects. Figure is a plot of capacitive load that will result in a degree phase margin versus noise gain for the AD8. Noise gain is the inverse of the feedback attenuation factor provided by the feedback network in use. V IN AD8. F V S. F pf k V OUT Figure. Extending Unity Gain Follower Capacitive Load Capability Beyond pf OFFSET VOLTAGE ADJUSTMENT The AD8 s offset voltage is low, so external offset voltage nulling is not usually required. Figure shows the recommended technique for AD8 s packaged in plastic DIPs. Adjusting offset voltage in this manner will change the offset voltage temperature drift by µv/ C for every millivolt of induced offset. The null pins are not functional for AD8s in the SO-8 R package. Figure. Small Signal Response of AD8 as Unity Gain Follower Driving pf Capacitive Load AD8 k V S Figure.

R F APPLICATIONS Single Supply Half-Wave and Full-Wave Rectifiers An AD8 configured as a unity gain follower and operated with a single supply can be used as a simple half-wave rectifier. The AD8 s inputs maintain picoamp level input currents even when driven well below the minus supply. The rectifier puts that behavior to good use, maintaining an input impedance of over Ω for input voltages from volt from the positive supply to volts below the negative supply. The full and half-wave rectifier shown in Figure operates as follows: when V IN is above ground, R is bootstrapped through the unity gain follower A and the loop of amplifier A. This forces the inputs of A to be equal, thus no current flows through R or R, and the circuit output tracks the input. When V IN is below ground, the output of A is forced to ground. The noninverting input of amplifier A sees the ground level output of A, therefore A operates as a unity gain inverter. The output at node C is then a full-wave rectified version of the input. Node B is a buffered half-wave rectified version of the input. Input voltages up to ± 8 volts can be rectified, depending on the voltage supply used.

F A AD8 C FULL-WAVE RECTIFIED OUTPUT B HALF-WAVE RECTIFIED OUTPUT Low Power Three-Pole Sallen Key Low-Pass Filter The AD8 s high input impedance makes it a good selection for active filters. High value resistors can be used to construct low frequency filters with capacitors much less than µf. The AD8 s picoamp level input currents contribute minimal dc errors. Figure shows an example, a Hz three-pole Sallen Key Filter. 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 two-pole section of the filter. This eliminates any peaking of the noise contribution of resistors R, R, and R, thus minimizing the inherent output voltage noise of the filter. A C. F B C V IN R k C. F R k R k. F C. F AD8.
