OPA2140AID 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 | Output, channel A; output short-circuit protected internally. |
| 2 | -IN A | input | Inverting input, channel A; voltage (V-) - 0.5 V to (V+) + 0.5 V, input current ±10 mA maximum. |
| 3 | +IN A | input | Noninverting input, channel A; voltage (V-) - 0.5 V to (V+) + 0.5 V, input current ±10 mA maximum. |
| 4 | V- | power_in | Negative (lowest) power supply; recommended ±2.25 V to ±18 V (dual supply) or 4.5 V to 36 V (single supply). |
| 5 | +IN B | input | Noninverting input, channel B; voltage (V-) - 0.5 V to (V+) + 0.5 V, input current ±10 mA maximum. |
| 6 | -IN B | input | Inverting input, channel B; voltage (V-) - 0.5 V to (V+) + 0.5 V, input current ±10 mA maximum. |
| 7 | OUT B | output | Output, channel B; output short-circuit protected internally. |
| 8 | V+ | power_in | Positive (highest) power supply; recommended ±2.25 V to ±18 V (dual supply) or 4.5 V to 36 V (single supply). |
