OPA342UA 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 | NC | unconnected | No internal connection on the OPA342 SO-8 package. |
| 2 | -In | input | Inverting input; common-mode range extends 300mV beyond the supply rails, and the input is diode-clamped to the rails with current limited to 10mA. |
| 3 | +In | input | Non-inverting input; common-mode range extends 300mV beyond the supply rails (-0.3V to (V+)+0.3V), and the input is diode-clamped to the rails with current limited to 10mA. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); total supply V+ to V- is specified 2.7V to 5.5V with an absolute maximum of 7.5V. |
| 5 | NC | unconnected | No internal connection on the OPA342 SO-8 package. |
| 6 | Out | output | Rail-to-rail amplifier output swinging to within 1mV of the rails with light loads, with short-circuit current of ±15mA. |
| 7 | V+ | power_in | Positive supply, specified 2.7V to 5.5V (operating 2.5V to 5.5V) and bypassed with 0.01µF ceramic capacitors. |
| 8 | NC | unconnected | No internal connection on the OPA342 SO-8 package. |
