# TSX561IYLT

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

TSX561IYLT 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 with rail-to-rail common-mode range from (VCC-) - 0.1 V to (VCC+) + 0.1 V. |
| 2 | VCC- | power_in | Negative supply voltage (ground in single-supply use); VCC total supply range is 3 V to 16 V. |
| 3 | IN- | input | Inverting input with rail-to-rail common-mode range from (VCC-) - 0.1 V to (VCC+) + 0.1 V. |
| 4 | OUT | output | Amplifier output, rail-to-rail with sink/source current typically 92 mA/90 mA at 16 V supply. |
| 5 | VCC+ | power_in | Positive supply voltage, 3 V to 16 V operating (18 V absolute maximum), with a 10 nF decoupling capacitor advised close to the pin. |
