OPA2343UA from Texas Instruments, in a SOIC-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 | OutA | output | Rail-to-rail output of amplifier A; swings to within 1mV of supply rails with 100kΩ load, short-circuit current ±50mA. |
| 2 | -InA | input | Inverting input of amplifier A; input bias current ±0.2pA typ / ±10pA max, must be current-limited to 10mA if driven >0.5V beyond supply rails. |
| 3 | +InA | input | Non-inverting input of amplifier A; common-mode range -0.3V to (V+)+0.3V, input bias current ±0.2pA typ / ±10pA max. |
| 4 | V- | power_in | Negative power supply (ground reference); supply voltage range 2.5V to 5.5V below V+; bypass with 0.01µF ceramic capacitor. |
| 5 | +InB | input | Non-inverting input of amplifier B; common-mode range -0.3V to (V+)+0.3V, input bias current ±0.2pA typ / ±10pA max. |
| 6 | -InB | input | Inverting input of amplifier B; input bias current ±0.2pA typ / ±10pA max, must be current-limited to 10mA if driven >0.5V beyond supply rails. |
| 7 | OutB | output | Rail-to-rail output of amplifier B; swings to within 1mV of supply rails with 100kΩ load, short-circuit current ±50mA. |
| 8 | V+ | power_in | Positive power supply; specified range 2.7V to 5V, operating range 2.5V to 5.5V, quiescent current 850µA typ / 1.25mA max per amplifier at VS=5V; bypass with 0.01µF ceramic capacitor. |
