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

OPA2690I-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 for channel A of the operational amplifier. |
| 2 | +In A | input | Non-inverting input for channel A of the operational amplifier. |
| 3 | DIS A | input | Disable control input for channel A; pull LOW to disable amplifier output to high-impedance state, or leave open or pull HIGH for normal operation. |
| 4 | -VS | power_in | Negative supply voltage (ground reference for single supply or negative rail for dual supply); ±2.5V to ±6V or +5V to +12V single supply. |
| 5 | DIS B | input | Disable control input for channel B; pull LOW to disable amplifier output to high-impedance state, or leave open or pull HIGH for normal operation. |
| 6 | +In B | input | Non-inverting input for channel B of the operational amplifier. |
| 7 | -In B | input | Inverting input for channel B of the operational amplifier. |
| 8 | Out A | output | High-current output for channel A with ±4.0V swing capability and 190mA drive current. |
| 9 | NC | unconnected | No connection. |
| 10 | NC | unconnected | No connection. |
| 11 | +VS | power_in | Positive supply voltage; +5V to +12V single supply or ±2.5V to ±6V dual supply. |
| 12 | NC | unconnected | No connection. |
| 13 | NC | unconnected | No connection. |
| 14 | Out B | output | High-current output for channel B with ±4.0V swing capability and 190mA drive current. |
