OPA380AIDR 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; not connected to the die internally. |
| 2 | -IN | input | Inverting input of the transimpedance amplifier; input bias current is ±50pA (max), input offset current ±100pA (max), and input signals exceeding the supply rails by more than ~500mV should be current-limited to 10mA to avoid damage. |
| 3 | +IN | input | Noninverting input, typically used as a fixed DC bias point; common-mode voltage range extends from V- to (V+) - 1.8V. |
| 4 | V- | power_in | Negative power-supply pin; specified voltage range (V+ to V-) is 2.7V to 5.5V, with an absolute maximum total supply voltage of +7V. |
| 5 | NC | unconnected | No internal connection; not connected to the die internally. |
| 6 | OUT | output | Amplifier output; swings to within 400mV-600mV of the positive rail and 60mV-100mV of the negative rail into a 2kΩ load, with a 150mA (typ) short-circuit current and 40Ω open-loop output impedance at 1MHz. |
| 7 | V+ | power_in | Positive power-supply pin; specified supply range is 2.7V to 5.5V with a quiescent current of 7.5mA (typ) / 9.5mA (max), 10mA max over temperature. |
| 8 | NC | unconnected | No internal connection; not connected to the die internally. |
