Analog Devices · FET Input Amplifiers · SOIC-8

AD823ARZ-R7 from Analog Devices, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT1 output Output of amplifier 1, which swings to within 50 mV of each rail for IOUT ≤ 100 µA and supplies 15 mA, 0.5 V from the rails.
2 -IN1 input Inverting input of amplifier 1, whose input common-mode range extends 0.2 V below -VS, and which needs a series current-limiting resistor if the input may exceed +VS by more than 300 mV.
3 +IN1 input Noninverting input of amplifier 1, whose common-mode range is -0.2 V to +3.8 V at +VS = +5 V, with a series resistor needed to avoid phase reversal for inputs above +VS.
4 -VS power_in Negative supply rail (ground in single-supply operation); the part operates from 3 V to 36 V single supply or ±1.5 V to ±18 V dual supply.
5 +IN2 input Noninverting input of amplifier 2, whose common-mode range is -0.2 V to +3.8 V at +VS = +5 V, with a series resistor needed to avoid phase reversal for inputs above +VS.
6 -IN2 input Inverting input of amplifier 2, whose input common-mode range extends 0.2 V below -VS, and which needs a series current-limiting resistor if the input may exceed +VS by more than 300 mV.
7 OUT2 output Output of amplifier 2, which swings to within 50 mV of each rail for IOUT ≤ 100 µA and supplies 15 mA, 0.5 V from the rails.
8 +VS power_in Positive supply rail; the part operates from 3 V to 36 V single supply or ±1.5 V to ±18 V dual supply, with absolute maximum supply voltage of 36 V.
