OPA4347UA from UMW, in a SOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUTA | output | Amplifier A output. Rail-to-rail; swings within ~5 mV of V+/V- into 100 kΩ. Short-circuit current ±17 mA (typ). |
| 2 | -INA | input | Amplifier A inverting input. Rail-to-rail input, extends 200 mV beyond supplies. Bias current ±0.5 pA (typ). |
| 3 | +INA | input | Amplifier A non-inverting input. Rail-to-rail input, extends 200 mV beyond supplies. |
| 4 | V+ | power_in | Positive supply. Single-supply range 2.3 V to 5.5 V (specified 2.5-5.5 V). Total V+ − V− must not exceed 7.5 V. |
| 5 | +INB | input | Amplifier B non-inverting input. Rail-to-rail input. |
| 6 | -INB | input | Amplifier B inverting input. Rail-to-rail input. |
| 7 | OUTB | output | Amplifier B output. Rail-to-rail. |
| 8 | OUTC | output | Amplifier C output. Rail-to-rail. |
| 9 | -INC | input | Amplifier C inverting input. Rail-to-rail input. |
| 10 | +INC | input | Amplifier C non-inverting input. Rail-to-rail input. |
| 11 | V- | power_in | Negative supply / ground for single-supply operation. Absolute maximum V+ − V− = 7.5 V. |
| 12 | +IND | input | Amplifier D non-inverting input. Rail-to-rail input. |
| 13 | -IND | input | Amplifier D inverting input. Rail-to-rail input. |
| 14 | OUTD | output | Amplifier D output. Rail-to-rail. |
