# TSX7191IYLT

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

TSX7191IYLT 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 | OUT | output | Op amp output with rail-to-rail swing, within 30 mV of the rails into a 10 kΩ load to VCC/2; the part is stable only at gain of 10 or more. |
| 2 | VCC- | power_in | Negative supply (ground in single-supply use); the input common-mode range extends from VCC- - 0.1 V. |
| 3 | IN+ | input | Non-inverting input with rail-to-rail common-mode range from VCC- - 0.1 V to VCC+ + 0.1 V; input current must be limited to 10 mA with a series resistor. |
| 4 | IN- | input | Inverting input with rail-to-rail common-mode range from VCC- - 0.1 V to VCC+ + 0.1 V; input current must be limited to 10 mA with a series resistor. |
| 5 | VCC+ | power_in | Positive supply, 2.7 V to 16 V operating (18 V absolute maximum), with a 22 nF decoupling capacitor recommended close to the pin. |
