OPA2344UA 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 | Out A | output | Output of amplifier A, rail-to-rail output swinging within 1mV of the supplies. |
| 2 | -In A | input | Inverting input of amplifier A, diode-clamped to the supply rails with input current limited to 10mA. |
| 3 | +In A | input | Non-inverting input of amplifier A, common-mode range extends 300mV beyond the supplies. |
| 4 | V- | power_in | Negative supply (ground in single-supply use); total supply V+ to V- is 2.5V to 5.5V operating, 7.5V absolute maximum. |
| 5 | +In B | input | Non-inverting input of amplifier B, common-mode range extends 300mV beyond the supplies. |
| 6 | -In B | input | Inverting input of amplifier B, diode-clamped to the supply rails with input current limited to 10mA. |
| 7 | Out B | output | Output of amplifier B, rail-to-rail output swinging within 1mV of the supplies. |
| 8 | V+ | power_in | Positive supply, operating range 2.5V to 5.5V above V-, 7.5V absolute maximum. |
