OPA191IDR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | NC | unconnected | No internal connection; can be left floating. |
| 2 | -IN | input | Inverting input with common-mode voltage range from (V-) - 0.1 V to (V+) + 0.1 V and differential input voltage range to supply rail. |
| 3 | +IN | input | Noninverting input with common-mode voltage range from (V-) - 0.1 V to (V+) + 0.1 V and differential input voltage range to supply rail. |
| 4 | V- | power_in | Negative (lowest) power supply supporting total supply voltage from 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply. |
| 5 | NC | unconnected | No internal connection; can be left floating. |
| 6 | OUT | output | Output with voltage swing from rail ranging from 5 mV to 500 mV depending on load impedance, maximum short-circuit current of ±65 mA. |
| 7 | V+ | power_in | Positive (highest) power supply supporting total supply voltage from 4.5 V to 36 V single supply or ±2.25 V to ±18 V dual supply. |
| 8 | NC | unconnected | No internal connection; can be left floating. |
