# OPA2691I-14DR

**Texas Instruments** · Operational Amplifier · SOIC-14

OPA2691I-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 | Channel A inverting input; the input signal range is limited to the common-mode input range of ±3.5V typical with ±5V supplies. |
| 2 | +In A | input | Channel A noninverting input, high-impedance (100 || 2 kΩ || pF typical) with input voltage range limited to ±VS. |
| 3 | DIS A | input | Channel A disable control; pulling LOW shuts the channel down to less than 150µA/ch with the output in a high-impedance state, while leaving open or holding HIGH gives normal operation. |
| 4 | -VS | power_in | Negative power supply; the device operates from ±2V to ±6V dual supply (±5V specified) with an absolute maximum of ±6.5V. |
| 5 | DIS B | input | Channel B disable control; pulling LOW shuts the channel down to less than 150µA/ch with the output in a high-impedance state, while leaving open or holding HIGH gives normal operation. |
| 6 | +In B | input | Channel B noninverting input, high-impedance (100 || 2 kΩ || pF typical) with input voltage range limited to ±VS. |
| 7 | -In B | input | Channel B inverting input; the input signal range is limited to the common-mode input range of ±3.5V typical with ±5V supplies. |
| 8 | Out B | output | Channel B output; drives up to ±190mA typical sourcing/sinking at VO = 0 and enters a high-impedance state when channel B is disabled. |
| 9 | NC | unconnected | No internal connection. |
| 10 | NC | unconnected | No internal connection. |
| 11 | +VS | power_in | Positive power supply; the device operates from +5V to +12V single supply or ±2.5V to ±6V dual supply, with an absolute maximum of ±6.5V. |
| 12 | NC | unconnected | No internal connection. |
| 13 | NC | unconnected | No internal connection. |
| 14 | Out A | output | Channel A output; drives up to ±190mA typical sourcing/sinking at VO = 0 and enters a high-impedance state when channel A is disabled. |
