OPA2343EA from Texas Instruments, in a VSSOP-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 | Out A | output | Output of amplifier A, which swings to within about 1 to 5 mV of the supply rails at a 100kΩ load, with short-circuit current continuous (one amplifier per package). |
| 2 | -In A | input | Inverting input of amplifier A; input signals that swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less. |
| 3 | +In A | input | Non-inverting input of amplifier A, whose common-mode range extends from -0.3V to (V+) + 0.3V. |
| 4 | V- | power_in | Negative supply rail (ground in single-supply operation); total supply operating range is 2.5V to 5.5V. |
| 5 | +In B | input | Non-inverting input of amplifier B, whose common-mode range extends from -0.3V to (V+) + 0.3V. |
| 6 | -In B | input | Inverting input of amplifier B; input signals that swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less. |
| 7 | Out B | output | Output of amplifier B, which swings to within about 1 to 5 mV of the supply rails at a 100kΩ load, with short-circuit current continuous (one amplifier per package). |
| 8 | V+ | power_in | Positive supply rail; specified from 2.7V to 5V (operating 2.5V to 5.5V), with power-supply pins bypassed by 0.01µF ceramic capacitors. |
