# OPA2683ID

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

OPA2683ID 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; the datasheet states a full ±4VPP swing on ±5V supplies into a 100Ω load. |
| 2 | -In A | input | Inverting input of amplifier A, which connects to the internal closed-loop input buffer with a 5.0Ω typical inverting input resistance (open-loop, DC). |
| 3 | +In A | input | Noninverting input of amplifier A; the common-mode input range is ±3.60V min over temperature at ±5V supplies. |
| 4 | -VS | power_in | Negative power supply; specified operating voltage is ±5V typ, maximum operating voltage ±6V, and absolute maximum supply ±6.5VDC. |
| 5 | +In B | input | Noninverting input of amplifier B; the common-mode input range is ±3.60V min over temperature at ±5V supplies. |
| 6 | -In B | input | Inverting input of amplifier B, which connects to the internal closed-loop input buffer with a 5.0Ω typical inverting input resistance (open-loop, DC). |
| 7 | Out B | output | Output of amplifier B; the datasheet states a full ±4VPP swing on ±5V supplies into a 100Ω load. |
| 8 | +VS | power_in | Positive power supply; specified operating voltage is ±5V typ, maximum operating voltage ±6V, and absolute maximum supply ±6.5VDC (single-supply operation +5V to +12V). |
