# TSX712IYDT

**STMicroelectronics** · Operational Amplifier · SO-8

TSX712IYDT from STMicroelectronics, in a SO-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 | Output of amplifier 1, which swings to within 40 mV of each rail when loaded with 10 kΩ to VCC/2 (rail-to-rail output). |
| 2 | IN1- | input | Inverting input of amplifier 1; the input common-mode range extends from (VCC-) - 0.1 V to (VCC+) + 0.1 V. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1; the input common-mode range extends from (VCC-) - 0.1 V to (VCC+) + 0.1 V, and input current must be limited by a series resistor if the input goes beyond the rails. |
| 4 | VCC- | power_in | Negative supply rail (ground reference, 0 V in the electrical characteristics tables). |
| 5 | IN2+ | input | Non-inverting input of amplifier 2; the input common-mode range extends from (VCC-) - 0.1 V to (VCC+) + 0.1 V. |
| 6 | IN2- | input | Inverting input of amplifier 2; the input common-mode range extends from (VCC-) - 0.1 V to (VCC+) + 0.1 V. |
| 7 | OUT2 | output | Output of amplifier 2, which swings to within 40 mV of each rail when loaded with 10 kΩ to VCC/2 (rail-to-rail output). |
| 8 | VCC+ | power_in | Positive supply, specified for 2.7 V to 16 V operation with an 18 V absolute maximum. |
