OPA348AIDBVR from Texas Instruments, in a SOT-23-5. 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 | OUT | output | Amplifier output. Rail-to-rail output stage; short-circuit current ±10 mA typical, drives capacitive loads per typical characteristics. |
| 2 | V- | power_in | Negative (lowest) power supply. Tie to GND for single-supply operation; total supply voltage (V+) - (V-) rated 2.1 V to 5.5 V (7.5 V absolute max). |
| 3 | +IN | input | Non-inverting (positive) input. Rail-to-rail common-mode range from (V-) - 0.2 V to (V+) + 0.2 V; input bias current ±0.5 pA typical. |
| 4 | -IN | input | Inverting (negative) input. Rail-to-rail common-mode range; inputs are not diode-clamped to the rails - limit signals exceeding rails by more than 0.5 V to ≤10 mA. |
| 5 | V+ | power_in | Positive (highest) power supply. Single-supply range 2.1 V to 5.5 V (7.5 V absolute max). Quiescent current 45 µA typical per amplifier. Bypass with 0.1 µF close to the pin. |
