OPA140AIDGKR from Texas Instruments, in a MSOP-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 | NC | unconnected | No internal connection; this pin can be left floating. |
| 2 | -IN | input | Inverting input of the amplifier; signal input pins are limited to (V-) - 0.5 V to (V+) + 0.5 V and ±10 mA input current. |
| 3 | +IN | input | Noninverting input of the amplifier; signal input pins are limited to (V-) - 0.5 V to (V+) + 0.5 V and ±10 mA input current, and the input range includes the V- supply. |
| 4 | V- | power_in | Negative (lowest) power supply; the device runs from 4.5 V to 36 V single-supply or ±2.25 V to ±18 V dual-supply. |
| 5 | NC | unconnected | No internal connection; this pin can be left floating. |
| 6 | OUT | output | Amplifier output, which is continuously short-circuit protected per the absolute maximum ratings. |
| 7 | V+ | power_in | Positive (highest) power supply; the absolute maximum single-supply voltage is 40 V and the dual-supply limit is ±20 V. |
| 8 | NC | unconnected | No internal connection; this pin can be left floating. |
