OPA374AIDR 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. May be left floating. |
| 2 | -IN | input | Inverting (negative) input of the operational amplifier. Common-mode input voltage range extends 200 mV beyond each supply rail; input bias current is typically <1 pA (10 pA max). |
| 3 | +IN | input | Non-inverting (positive) input of the operational amplifier. Common-mode input voltage range extends 200 mV beyond each supply rail; input bias current is typically <1 pA (10 pA max). |
| 4 | V- | power_in | Negative (most negative) power supply. For single-supply operation tie to GND; for dual-supply operation tie to the negative rail. Total supply voltage (V+) − (V−) must be between 2.3 V and 5.5 V (2.7 V to 5.5 V recommended). |
| 5 | NC | unconnected | No internal connection. May be left floating. |
| 6 | OUT | output | Amplifier output. Rail-to-rail output stage swings within 25 mV of each supply rail; slew rate is 5 V/µs and short-circuit current is typically ±65 mA. |
| 7 | V+ | power_in | Positive (most positive) power supply. Operating voltage range 2.3 V to 5.5 V referenced to V−; bypass to V− with a 0.1-µF ceramic capacitor placed close to the pin. |
| 8 | NC | unconnected | No internal connection. May be left floating. |
