OPA604AU from Texas Instruments, 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 | Offset Trim | passive | Offset null pin used with a trim potentiometer (50kΩ to 1MΩ, 100kΩ recommended) for about ±50mV typical trim range; may be left unconnected. |
| 2 | -In | input | Inverting input; input voltage must stay within (V-)-1V to (V+)+1V, with typical common-mode range of ±13V at VS=±15V. |
| 3 | +In | input | Non-inverting input; input voltage must stay within (V-)-1V to (V+)+1V, with typical common-mode range of ±13V at VS=±15V. |
| 4 | -VS | power_in | Negative supply; operating voltage range is ±4.5V to ±24V total supply with absolute maximum ±25V, and a 1µF tantalum capacitor at the pin is usually adequate for decoupling. |
| 5 | Offset Trim | passive | Offset null pin used with a trim potentiometer (50kΩ to 1MΩ, 100kΩ recommended) for about ±50mV typical trim range; may be left unconnected. |
| 6 | Output | output | Op amp output that drives a 600Ω load to typically ±11V to ±12V, with short-circuit current of about ±40mA and continuous short circuit to ground allowed. |
| 7 | +VS | power_in | Positive supply; operating voltage range is ±4.5V to ±24V total supply with absolute maximum ±25V, and a 1µF tantalum capacitor at the pin is usually adequate for decoupling. |
| 8 | NC | unconnected | No internal connection. |
