**Texas Instruments** · Precision Op Amps · SOIC-8

TLC1078IDR 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 | 1OUT | output | Output of amplifier 1, with output drive capability greater than 20 mA and output swing to the negative rail. |
| 2 | 1IN- | input | Inverting input of amplifier 1, a high-impedance LinCMOS input with typical input bias current of 0.6 pA. |
| 3 | 1IN+ | input | Noninverting input of amplifier 1, a high-impedance LinCMOS input whose common-mode range extends below the negative rail. |
| 4 | GND | power_in | Ground / negative supply pin of the device. |
| 5 | 2IN+ | input | Noninverting input of amplifier 2, a high-impedance LinCMOS input whose common-mode range extends below the negative rail. |
| 6 | 2IN- | input | Inverting input of amplifier 2, a high-impedance LinCMOS input with typical input bias current of 0.6 pA. |
| 7 | 2OUT | output | Output of amplifier 2, with output drive capability greater than 20 mA and output swing to the negative rail. |
| 8 | VDD | power_in | Positive supply pin, operating from a supply voltage of 1.4 V minimum. |
