**Texas Instruments** · Operational Amplifier · SOT-23-6

OPA691IDBVT from Texas Instruments, in a SOT-23-6. 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 | output | Amplifier output; output swing is specified at ±4.0 V typical with no load and at least ±3.8 V (25°C) with no load, and the output goes high impedance when the DIS pin is pulled LOW. |
| 2 | -VS | power_in | Negative power supply; the device is specified for dual supplies of ±2.5 V to ±6 V with a maximum operating voltage of ±6 V and an absolute maximum power supply of ±6.5 V DC. |
| 3 | Noninverting Input | input | High-impedance noninverting input with a common-mode input range of ±3.5 V typical (±3.4 V minimum at 25°C), and the absolute maximum differential input voltage is ±1.2 V. |
| 4 | Inverting Input | input | Inverting input with an open-loop inverting input resistance of 35 Ω typical; the absolute maximum differential input voltage is ±1.2 V. |
| 5 | DIS | input | Disable control: pulling this pin LOW (below 1.5 V to 1.8 V max disable voltage) drops the supply current below 150 µA and places the output in a high-impedance state, while leaving it open or HIGH gives normal operation. |
| 6 | +VS | power_in | Positive power supply; the device is specified for dual supplies of ±2.5 V to ±6 V or single supply from +5 V to +12 V, with a maximum operating voltage of ±6 V and an absolute maximum power supply of ±6.5 V DC. |
