OPA377AIDR from Texas Instruments, in a SOP-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. |
| 2 | -IN | input | Inverting input; common-mode range extends 100mV beyond the supply rails and the input is diode-clamped to the rails, so limit input current to 10mA. |
| 3 | +IN | input | Non-inverting input; common-mode range extends 100mV beyond the supply rails and the input is diode-clamped to the rails, so limit input current to 10mA. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); total supply VS = (V+) - (V-) is specified from 2.2V to 5.5V, with 7V absolute maximum. |
| 5 | NC | unconnected | No internal connection. |
| 6 | OUT | output | Rail-to-rail amplifier output; unity-gain stable, drives up to 250pF directly and short-circuit current is +30/-50mA. |
| 7 | V+ | power_in | Positive supply, 2.2V to 5.5V with respect to V-; connect a 0.1µF bypass capacitor close to the pin. |
| 8 | NC | unconnected | No internal connection. |
