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

TLC2272QPWRQ1 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 channel 1; output current is limited to ±50 mA and the output can be shorted to either supply for an unlimited duration at or below 25°C. |
| 2 | 1IN- | input | Inverting input of channel 1; input voltage must stay between VDD− and VDD+ − 1.5 V, and input current is limited to ±5 mA. |
| 3 | 1IN+ | input | Noninverting input of channel 1; input voltage must stay between VDD− and VDD+ − 1.5 V, and input current is limited to ±5 mA. |
| 4 | VDD- | power_in | Negative (lowest) supply rail; absolute maximum is -8 V with respect to the midpoint between VDD+ and VDD−. |
| 5 | 2IN+ | input | Noninverting input of channel 2; input voltage must stay between VDD− and VDD+ − 1.5 V, and input current is limited to ±5 mA. |
| 6 | 2IN- | input | Inverting input of channel 2; input voltage must stay between VDD− and VDD+ − 1.5 V, and input current is limited to ±5 mA. |
| 7 | 2OUT | output | Output of channel 2; output current is limited to ±50 mA and the output can be shorted to either supply for an unlimited duration at or below 25°C. |
| 8 | VDD+ | power_in | Positive (highest) supply rail; absolute maximum is 8 V and the recommended supply range is ±2.2 V to ±8 V. |
