# TSB7191AILT

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

TSB7191AILT 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 | Output channel of the op-amp; rail-to-rail output. |
| 2 | VCC- | power_in | Negative supply voltage (ground in single-supply use); supply range 2.7 V to 36 V total. |
| 3 | IN+ | input | Non-inverting input channel; rail-to-rail common mode range (VCC-) to (VCC+) + 0.1 V. |
| 4 | IN- | input | Inverting input channel; input voltage limited to (VCC-) - 0.2 V to (VCC+) + 0.2 V absolute maximum. |
| 5 | VCC+ | power_in | Positive supply voltage; operating 2.7 V to 36 V, absolute maximum +40 V. |
