3PEAK · Operational Amplifier · SOT-23-5
TP2191-TR from 3PEAK, 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 | Amplifier output; the voltage range extends to within milli-volts of each supply rail. |
| 2 | V- | power_in | Negative power supply, normally tied to ground; the voltage between V+ and V- must be between 1.8V and 5.5V. |
| 3 | +IN | input | Non-inverting amplifier input with a voltage range from V- - 0.3V to V+ + 0.3V. |
| 4 | -IN | input | Inverting amplifier input with a voltage range from V- - 0.3V to V+ + 0.3V. |
| 5 | V+ | power_in | Positive power supply, typically 1.8V to 5.5V; a 0.1 μF bypass capacitor should be placed as close to the part as possible. |
