AD8397ARDZ

Analog Devices · Operational Amplifier · SOIC-8-EP

AD8397ARDZ from Analog Devices, in a SOIC-8-EP. 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; the rail-to-rail output swings to within 0.5 V of either supply rail while driving a 25 Ω load.
2 -IN1 input Inverting input of amplifier 1, part of the H-bridge input stage; use the amplifier at a gain of two or greater to avoid overdriving the input.
3 +IN1 input Non-inverting input of amplifier 1, part of the H-bridge input stage with a specified input resistance of 87 kΩ and input capacitance of 1.4 pF.
4 -VS power_in Negative supply pin; the AD8397 operates from a dual supply of ±1.5 V to ±12 V, with an absolute maximum supply voltage of 26.4 V.
5 +IN2 input Non-inverting input of amplifier 2, part of the H-bridge input stage with a specified input resistance of 87 kΩ and input capacitance of 1.4 pF.
6 -IN2 input Inverting input of amplifier 2, part of the H-bridge input stage; use the amplifier at a gain of two or greater to avoid overdriving the input.
7 OUT2 output Output of amplifier 2; the rail-to-rail output delivers up to 310 mA peak into 32 Ω on ±12 V supplies, a peak AC rating not valid for continuous DC operation.
8 +VS power_in Positive supply pin; the AD8397 operates from a dual supply of ±1.5 V to ±12 V and should be decoupled with a 0.1 µF MLCC located no more than 1/8 inch away.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
