Precision Micropower, Low Noise CMOS Rail-to-Rail Input/Output Operational Amplifiers FEATURES Low offset voltage: μv max Low input bias current: 1 pa max Single-supply operation: 1.8 V to 5 V Low noise: 22 nv/ Hz Micropower: μa max Low distortion No phase reversal Unity gain stable APPLICATIONS Battery-powered instrumentation Multipole filters Sensors Low power ASIC input or output amplifiers GENERAL DESCRIPTION The are single/dual/quad micropower rail-to-rail input and output amplifiers, respectively, that feature very low offset voltage as well as low input voltage and current noise. These amplifiers use a patented trimming technique that achieves superior precision without laser trimming. The parts are fully specified to operate from 1.8 V to 5. V single supply or from ±.9 V to ±2.5 V dual supply. The combination of low offsets, low noise, very low input bias currents, and low power consumption make the especially useful in portable and loop-powered instrumentation. The ability to swing rail-to-rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in low power, single-supply systems. The AD863 is available in a tiny 5-lead TSOT-23 package. The AD867 is available in 8-lead MSOP and 8-lead SOIC packages. The AD869 is available in 14-lead TSSOP and 14-lead SOIC packages.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ESD CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Rev. B Page 5 of 2

APPLICATIONS NO PHASE REVERSAL The do not exhibit phase inversion even when the input voltage exceeds the maximum input common-mode voltage. Phase reversal can cause permanent damage to the amplifier, resulting in system lockups. The can handle voltages of up to 1 V over the supply. V IN V IN = 6V p-p A V = 1 R L = kω The use of the snubber circuit is usually recommended for unity gain configurations. Higher gain configurations help improve the stability of the circuit. Figure 44 shows the same output response with the snubber in place. V S = ±.9V V IN = mv C L = 2nF R L = kω VOLTAGE (1V/DIV) V OUT 4356-42 Figure 42.

No Phase Response INPUT OVERVOLTAGE PROTECTION If a voltage 1 V higher than the supplies is applied at either input, the use of a limiting series resistor is recommended. If both inputs are used, each one should be protected with a series resistor. To ensure good protection, the current should be limited to a maximum of 5 ma. The value of the limiting resistor can be determined from the equation (VIN VS)/(RS + 2 Ω) 5 ma 2mV + V V+ R S 1Ω V CC C S 47pF Figure 43.

Figure 42 shows the output of the in response to a mv input signal, with a 2 nf capacitive load. Although it is configured in positive unity gain (the worst case), the AD863 shows less than 2% overshoot. Simple additional circuitry can eliminate ringing and overshoot. Figure 44. Output Response to a 2 nf Capacitive Load, With Snubber 4356-44 One technique is the snubber network, which consists of a series RC and a resistive load (see Figure 43). With the snubber in place, the are capable of driving capacitive loads of 2 nf with no ringing and less than 3% overshoot. Rev. B Page 12 of 2

One of the most common applications is liquid level sensing in tanks. This is particularly popular in pharmaceutical environments where a tank must know when to stop filling or mixing a given liquid. In aerospace applications, these sensors detect the level of oxygen used to propel engines. Whether in a combustible environment or not, capacitive sensors generally use low voltage. The precision and low voltage of the make the parts an excellent choice for such applications. R1 1kΩ V IN V V+ R2 V EE 99kΩ V CC AD863 R3 1kΩ V CC U5 V+ AD8541 V V EE R4 99kΩ Figure 45. High Gain Composite Amplifier 4356-45 COMPOSITE AMPLIFIERS A composite amplifier can provide a very high gain in applications where high closed-loop dc gains are needed. The high gain achieved by the composite amplifier comes at the expense of a loss in phase margin. Placing a small capacitor, CF, in the feedback in parallel with R2 ( Figure 45) improves the phase margin. Picking CF = pf yields a phase margin of about 45 for the values shown in Figure 45. A composite amplifier can be used to optimize dc and ac characteristics. Figure 46 shows an example using the AD863 and the AD8541. This circuit offers many advantages. The bandwidth is increased substantially, and the input offset voltage and noise of the AD8541 become insignificant since they are divided by the high gain of the AD863. The circuit of Figure 46 offers a high bandwidth (nearly double that of the AD863), a high output current, and a very low power consumption of less than μa.

BATTERY-POWERED APPLICATIONS The are ideal for battery-powered applications. The parts are tested at 5 V, 3.3 V, 2.7 V, and 1.8 V and are suitable for various applications whether in single or dual supply. In addition to their low offset voltage and low input bias, the have a very low supply current of 4 μa, making the parts an excellent choice for portable electronics. The TSOT package allows the AD863 to be used on smaller board spaces. PHOTODIODES Photodiodes have a wide range of applications from bar code scanners to precision light meters and CAT scanners. The very low noise and low input bias current of the AD863/AD867/ AD869 make the parts very attractive amplifiers for I-V conversion applications. Figure 47 shows a simple photodiode circuit. The feedback capacitor helps the circuit maintain stability. The signal bandwidth can be increased at the expense of an increase in the total noise; a low-pass filter can be implemented by a simple RC network at the output to reduce the noise. The signal bandwidth can be calculated by ½πR2C2 and the closed-loop bandwidth is the intersection point of the open-loop gain and the noise gain. The circuit shown in Figure 47 has a closed-loop bandwidth of 58 khz and a signal bandwidth of 16 Hz. Increasing C2 to pf yields a closed-loop bandwidth of 65 khz, but only 3.2 Hz of signal bandwidth can be achieved. C2 pf R2 MΩ V CC R1 MΩ C1 pf AD863 V EE 4356-47 Figure 47. Photodiode Circuit Rev.
