OPA2674I-14DR 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 | -In A | input | Inverting input of amplifier A; common-mode input range is ±4.5V on ±6V supplies. |
| 2 | +In A | input | Noninverting input of amplifier A; input impedance is 250kΩ |
| 3 | A0 | input | Power control logic input A0, referenced to +VS; with A1 sets full power, cutback, idle or shutdown, and left unconnected gives full power. |
| 4 | -VS | power_in | Negative power supply; absolute maximum total supply is ±6.5V. |
| 5 | A1 | input | Power control logic input A1, referenced to +VS; pulling low with A0 selects cutback, idle or shutdown, and left unconnected gives full power. |
| 6 | +In B | input | Noninverting input of amplifier B; input impedance is 250kΩ |
| 7 | -In B | input | Inverting input of amplifier B; common-mode input range is ±4.5V on ±6V supplies. |
| 8 | Out B | output | Output of amplifier B; delivers ±500mA typical output current with ±800mA typical short-circuit current limit. |
| 9 | NC | unconnected | No connection. |
| 10 | NC | unconnected | No connection. |
| 11 | +VS | power_in | Positive power supply; absolute maximum total supply is ±6.5V and it should be decoupled with 0.1µF close to the pin. |
| 12 | NC | unconnected | No connection. |
| 13 | NC | unconnected | No connection. |
| 14 | Out A | output | Output of amplifier A; delivers ±500mA typical output current with ±800mA typical short-circuit current limit. |
