Analog Devices · FET Input Amplifiers · SOIC-8

AD823ARZ 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 can source or sink 15 mA while 0.5 V from the supply rails.
2 -IN1 input Inverting input of amplifier 1, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS.
3 +IN1 input Non-inverting input of amplifier 1, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS.
4 -VS power_in Negative supply rail; the part operates from a single supply of 3.0 V to 36 V (with −VS as ground) or from dual supplies of ±1.5 V to ±18 V.
5 +IN2 input Non-inverting input of amplifier 2, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS.
6 -IN2 input Inverting input of amplifier 2, a JFET input with input bias current below 25 pA maximum; the input voltage range extends 0.2 V below −VS.
7 OUT2 output Output of amplifier 2, which swings to within 50 mV of each rail for IOUT ≤ 100 µA and can source or sink 15 mA while 0.5 V from the supply rails.
8 +VS power_in Positive supply rail; the part operates from a single supply of 3.0 V to 36 V or from dual supplies of ±1.5 V to ±18 V.
