**Texas Instruments** · Operational Amplifier · SOIC-8

OPA2674IDR 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 | Channel A output, delivers ±500mA typ output current (±380mA min at +25°C) with ±800mA typ short-circuit current limit. |
| 2 | -In A | input | Channel A inverting input; differential input voltage limited to ±1.2V and common-mode within ±VS, with ESD rating >500V HBM. |
| 3 | +In A | input | Channel A noninverting input; differential input voltage limited to ±1.2V, common-mode range ±VS absolute maximum (±4.5V typ CMIR at ±6V supplies). |
| 4 | -VS | power_in | Negative power supply (ground in single-supply operation); total supply to +VS is limited to ±6.5V absolute maximum. |
| 5 | +In B | input | Channel B noninverting input; differential input voltage limited to ±1.2V, common-mode range ±VS absolute maximum (±4.5V typ CMIR at ±6V supplies). |
| 6 | -In B | input | Channel B inverting input; differential input voltage limited to ±1.2V and common-mode within ±VS, with ESD rating >500V HBM. |
| 7 | Out B | output | Channel B output, delivers ±500mA typ output current (±380mA min at +25°C) with ±800mA typ short-circuit current limit. |
| 8 | +VS | power_in | Positive power supply; specified at ±6V (+12V single supply) with ±6.5V absolute maximum supply. |
