**STMicroelectronics** · Operational Amplifier · TSSOP-14

TSX634AIPT from STMicroelectronics, in a TSSOP-14. 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, rail-to-rail. |
| 2 | IN1- | input | Inverting input of amplifier 1; input current must be limited to 10 mA by a series resistor. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1; common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 4 | VCC+ | power_in | Positive supply, 3.3 V to 16 V operating (18 V absolute maximum); decouple with 10 nF close to the pin. |
| 5 | IN2+ | input | Non-inverting input of amplifier 2; common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 6 | IN2- | input | Inverting input of amplifier 2; input current must be limited to 10 mA by a series resistor. |
| 7 | OUT2 | output | Output of amplifier 2, rail-to-rail. |
| 8 | OUT3 | output | Output of amplifier 3, rail-to-rail. |
| 9 | IN3- | input | Inverting input of amplifier 3; input current must be limited to 10 mA by a series resistor. |
| 10 | IN3+ | input | Non-inverting input of amplifier 3; common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 11 | VCC- | power_in | Negative supply (ground in single-supply use); decouple with 10 nF close to the pin. |
| 12 | IN4+ | input | Non-inverting input of amplifier 4; common mode range VCC- - 0.1 V to VCC+ + 0.1 V. |
| 13 | IN4- | input | Inverting input of amplifier 4; input current must be limited to 10 mA by a series resistor. |
| 14 | OUT4 | output | Output of amplifier 4, rail-to-rail. |
