OPA347NA 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 | Out | output | Output of the amplifier, which swings within 5mV of the rails for light loads (>100kΩ) and can directly drive up to 250pF in unity gain. |
| 2 | V- | power_in | Negative power supply (ground in single-supply operation), with inputs allowed to range 200mV beyond this rail and an absolute maximum input of 500mV beyond the supplies. |
| 3 | +In | input | Non-inverting input; normal operation is limited to a common-mode range of (V-) - 0.2V to (V+) + 0.2V. |
| 4 | -In | input | Inverting input; input current should be limited to 10mA when signals exceed the supply rails by more than 0.5V. |
| 5 | V+ | power_in | Positive power supply; the device is specified from 2.5V to 5.5V with a minimum operating voltage of 2.3V, and should be bypassed with 0.01µF ceramic capacitors. |
