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). |
