Analog Devices · FET Input Amplifiers · SOIC-8-EP

ADA4625-1ARDZ 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 NC unconnected No connect; do not connect to this pin.
2 -IN input Inverting input of the amplifier.
3 +IN input Noninverting input of the amplifier.
4 V- power_in Negative supply voltage; the input common-mode range includes this pin, and single-supply operation is 5 V to 36 V total.
5 NC unconnected No connect; do not connect to this pin.
6 OUT output Amplifier output, which swings rail to rail and can drive loads up to 1000 pF and/or 600 Ω.
7 V+ power_in Positive supply voltage; operates from +5 V to +36 V single supply (±2.5 V to ±18 V dual supply).
8 NC unconnected No connect; do not connect to this pin.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
