OPA338UA from UMW, in a SOP-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. Leave floating or tie to any convenient potential. |
| 2 | -In | input | Inverting input of the op-amp. High-impedance CMOS/FET input (~10^13 ohm), input bias current typ +/-0.2 pA, max +/-10 pA. Input voltage must remain within (V-) - 0.5V to (V+) + 0.5V. |
| 3 | +In | input | Non-inverting input of the op-amp. Common-mode range extends from (V-) - 0.2V up to (V+) - 1.2V. High-impedance FET input, 10 pA max bias. |
| 4 | V- | power_in | Negative supply rail. For single-supply operation, tie to GND. Total supply voltage (V+) - (V-) must be within 2.5V to 5.5V (7.5V absolute max). |
| 5 | NC | unconnected | No internal connection. |
| 6 | Output | output | Rail-to-rail op-amp output. Swings within ~40 mV (typ) of each rail into RL=25 kohm. Short-circuit current +/-9 mA typ; short to ground is continuous-safe. |
| 7 | V+ | power_in | Positive supply rail. 2.5V to 5.5V specified operation, 7.5V absolute max across V+ to V-. Quiescent current typ 525 uA. |
| 8 | NC | unconnected | No internal connection. |
