OPA4684IDR from Texas Instruments, in a SOIC-14. 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 | Output A | output | Channel A amplifier output, with 120mA output current capability. |
| 2 | -Input A | input | Channel A inverting input, the low-impedance current-feedback input (about 4.0Ω open-loop) that connects to the feedback resistor. |
| 3 | +Input A | input | Channel A noninverting input with 50kΩ |
| 4 | +V | power_in | Positive supply, +5V to +12V single-supply or +2.5V to +6.0V dual-supply operation, with a 0.1µF decoupling capacitor placed within 0.25". |
| 5 | +Input B | input | Channel B noninverting input with 50kΩ |
| 6 | -Input B | input | Channel B inverting input, the low-impedance current-feedback input that connects to the feedback resistor. |
| 7 | Output B | output | Channel B amplifier output, with 120mA output current capability. |
| 8 | Output C | output | Channel C amplifier output, with 120mA output current capability. |
| 9 | -Input C | input | Channel C inverting input, the low-impedance current-feedback input that connects to the feedback resistor. |
| 10 | +Input C | input | Channel C noninverting input with 50kΩ |
| 11 | -V | power_in | Negative supply (ground in single-supply operation); total supply across the pins must not exceed ±6.5V absolute maximum. |
| 12 | +Input D | input | Channel D noninverting input with 50kΩ |
| 13 | -Input D | input | Channel D inverting input, the low-impedance current-feedback input that connects to the feedback resistor. |
| 14 | Output D | output | Channel D amplifier output, with 120mA output current capability. |
