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

TL972QPWRQ1 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 | OUT1 | output | Amplifier 1 rail-to-rail output, swinging to ±2.4 V typ at VCC = ±2.5 V with RL = 2 kΩ. |
| 2 | IN1- | input | Amplifier 1 inverting input; differential input voltage limited to ±1 V and input range VCC- - 0.3 V to VCC+ + 0.3 V. |
| 3 | IN1+ | input | Amplifier 1 noninverting input; common-mode range is VCC- + 1.15 V to VCC+ - 1.15 V. |
| 4 | VCC- | power_in | Negative supply (ground for single supply); total supply voltage 2.7 V to 12 V recommended, 15 V absolute maximum. |
| 5 | IN2+ | input | Amplifier 2 noninverting input; common-mode range is VCC- + 1.15 V to VCC+ - 1.15 V. |
| 6 | IN2- | input | Amplifier 2 inverting input; differential input voltage limited to ±1 V and input range VCC- - 0.3 V to VCC+ + 0.3 V. |
| 7 | OUT2 | output | Amplifier 2 rail-to-rail output, swinging to ±2.4 V typ at VCC = ±2.5 V with RL = 2 kΩ. |
| 8 | VCC+ | power_in | Positive supply; total supply voltage 2.7 V to 12 V recommended, 15 V absolute maximum. |
