OPA344NA from Texas Instruments, in a SOT-23-5. 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 | V+ | power_in | Positive supply voltage with operating range 2.7V to 5.5V and maximum quiescent current 250µA. |
| 2 | -In | input | Inverting input terminal with input bias current ±10pA maximum and common-mode voltage range -0.3V to (V+)+0.3V. |
| 3 | Out | output | Output with voltage swing from rail 1mV to 400mV and short-circuit current ±15mA. |
| 4 | +In | input | Non-inverting input terminal with input bias current ±10pA maximum and common-mode voltage range -0.3V to (V+)+0.3V. |
| 5 | V- | power_in | Negative supply voltage serving as ground reference. |
