OPA343UA from Texas Instruments, in a SOP-8. 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 | NC | unconnected | Shown as NC (no connect) on the SO-8 pin diagram; the datasheet gives no function or electrical limit for this pin. |
| 2 | -In | input | Inverting input; the input terminals are diode-clamped to the supply rails, and input signals more than 0.5V beyond the rails should be limited to 10mA or less. |
| 3 | +In | input | Non-inverting input; the common-mode voltage range extends from -0.3V to (V+) + 0.3V. |
| 4 | V- | power_in | Negative power supply (ground in single-supply operation); the device operates from a single supply of 2.5V to 5.5V. |
| 5 | NC | unconnected | Shown as NC (no connect) on the SO-8 pin diagram; the datasheet gives no function or electrical limit for this pin. |
| 6 | Output | output | Output swings to within 1mV of the supply rails with a 100kΩ load, with short-circuit current of ±50mA and continuous short-circuit tolerance (one amplifier per package). |
| 7 | V+ | power_in | Positive power supply; specified from 2.7V to 5.5V (operating range 2.5V to 5.5V), absolute maximum supply 7.5V. |
| 8 | NC | unconnected | Shown as NC (no connect) on the SO-8 pin diagram; the datasheet gives no function or electrical limit for this pin. |
