**STMicroelectronics** · Operational Amplifier · SOT-23-5

TSX561AIYLT from STMicroelectronics, in a SOT-23-5. 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 | IN+ | input | Non-inverting input; common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V, rail-to-rail, with input current limited to 10 mA by a series resistor. |
| 2 | VCC- | power_in | Negative supply (ground in single-supply use); 10 nF decoupling capacitor advised close to the supply pins. |
| 3 | IN- | input | Inverting input; common-mode range (VCC-) - 0.1 V to (VCC+) + 0.1 V, rail-to-rail, with input current limited to 10 mA by a series resistor. |
| 4 | OUT | output | Amplifier output; sinks 11 mA typ. 14 mA and sources 9 mA min. 12 mA typ. at 5 V, swinging within 70 mV max of the rails at 25 °C with RL = 10 kΩ. |
| 5 | VCC+ | power_in | Positive supply, operating range 3 V to 16 V (absolute maximum 18 V); 10 nF decoupling capacitor advised close to the supply pins. |
