**Texas Instruments** · Operational Amplifier · SOIC-8

TLC2272ACD 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 channel 1. |
| 2 | 1IN- | input | Inverting input of channel 1; input voltage range is VDD− to VDD+ − 1.5 V. |
| 3 | 1IN+ | input | Non-inverting input of channel 1; input voltage range is VDD− to VDD+ − 1.5 V. |
| 4 | VDD−/GND | power_in | Negative (lowest) supply, labeled VDD−/GND on the D package. |
| 5 | 2IN+ | input | Non-inverting input of channel 2; input voltage range is VDD− to VDD+ − 1.5 V. |
| 6 | 2IN- | input | Inverting input of channel 2; input voltage range is VDD− to VDD+ − 1.5 V. |
| 7 | 2OUT | output | Output of channel 2. |
| 8 | VDD+ | power_in | Positive (highest) supply; the datasheet specifies VDD± from ±2.2 V to ±8 V for C-level parts. |
