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

TLC27L4ACDR 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 | 1OUT | output | Output of channel 1; absolute maximum output current is ±30 mA per output. |
| 2 | 1IN- | input | Inverting input of channel 1. |
| 3 | 1IN+ | input | Non-inverting input of channel 1. |
| 4 | VDD | power_in | Positive (highest) power supply; the C-suffix operating range is 3 V to 16 V and the I-suffix range is 4 V to 16 V. |
| 5 | 2IN+ | input | Non-inverting input of channel 2. |
| 6 | 2IN- | input | Inverting input of channel 2. |
| 7 | 2OUT | output | Output of channel 2; absolute maximum output current is ±30 mA per output. |
| 8 | 3OUT | output | Output of channel 3; absolute maximum output current is ±30 mA per output. |
| 9 | 3IN- | input | Inverting input of channel 3. |
| 10 | 3IN+ | input | Non-inverting input of channel 3. |
| 11 | GND | power_in | Ground or negative (lowest) power supply; the common-mode input range extends below the negative supply rail for C and I suffix types. |
| 12 | 4IN+ | input | Non-inverting input of channel 4. |
| 13 | 4IN- | input | Inverting input of channel 4. |
| 14 | 4OUT | output | Output of channel 4; absolute maximum output current is ±30 mA per output. |
