OPA2191IDR 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 | OUT A | output | Output of operational amplifier channel A with ±65 mA short-circuit current capability at VS = ±18 V and 5 to 110 mV rail-to-rail voltage swing. |
| 2 | -IN A | input | Inverting input of channel A with common-mode voltage range from (V-) - 0.1 V to (V+) + 0.1 V and input bias current ±5 pA typical. |
| 3 | +IN A | input | Noninverting input of channel A with common-mode voltage range from (V-) - 0.1 V to (V+) + 0.1 V and input bias current ±5 pA typical. |
| 4 | V- | power_in | Negative (lowest) power supply operating from ±2.25 V to ±18 V (single supply 4.5 V to 36 V) over -40°C to +125°C ambient temperature range. |
| 5 | +IN B | input | Noninverting input of channel B with common-mode voltage range from (V-) - 0.1 V to (V+) + 0.1 V and input bias current ±5 pA typical. |
| 6 | -IN B | input | Inverting input of channel B with common-mode voltage range from (V-) - 0.1 V to (V+) + 0.1 V and input bias current ±5 pA typical. |
| 7 | OUT B | output | Output of operational amplifier channel B with ±65 mA short-circuit current capability at VS = ±18 V and 5 to 110 mV rail-to-rail voltage swing. |
| 8 | V+ | power_in | Positive (highest) power supply operating from ±2.25 V to ±18 V (single supply 4.5 V to 36 V) over -40°C to +125°C ambient temperature range. |
