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

TLC272CPWR from Texas Instruments, in a TSSOP-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; output range includes the negative supply rail. |
| 2 | 1IN- | input | Inverting input of amplifier 1; input voltage range -0.3 V to VDD. |
| 3 | 1IN+ | input | Noninverting input of amplifier 1; common-mode range extends to -0.2 V at VDD = 5 V to 3.5 V. |
| 4 | GND | power_in | Ground / negative supply rail; the device is optimized for single-supply operation. |
| 5 | 2IN+ | input | Noninverting input of amplifier 2; common-mode range extends to -0.2 V at VDD = 5 V to 3.5 V. |
| 6 | 2IN- | input | Inverting input of amplifier 2; input voltage range -0.3 V to VDD. |
| 7 | 2OUT | output | Output of amplifier 2; output range includes the negative supply rail. |
| 8 | VDD | power_in | Positive supply; 3 V to 16 V for C suffix, absolute maximum 18 V. |
