OPA2890IDR 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 | Out A | output | Channel A amplifier output, which can deliver over 30mA drive current on a single +5V supply. |
| 2 | -In A | input | Channel A inverting input, with input voltage range of ±VS. |
| 3 | +In A | input | Channel A non-inverting input, with input voltage range of ±VS. |
| 4 | -VS | power_in | Negative supply (ground in single-supply use), with total supply of +3V to +12V single or ±1.5V to ±6V dual and an absolute maximum of ±6.5V. |
| 5 | +In B | input | Channel B non-inverting input, with input voltage range of ±VS. |
| 6 | -In B | input | Channel B inverting input, with input voltage range of ±VS. |
| 7 | Out B | output | Channel B amplifier output, which can deliver over 30mA drive current on a single +5V supply. |
| 8 | +VS | power_in | Positive supply, with total supply of +3V to +12V single or ±1.5V to ±6V dual and an absolute maximum of ±6.5V. |
