3PEAK · Operational Amplifier · SOT-23-5
TP1281L1-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, which swings rail-to-rail; the output enters high impedance when die temperature reaches around 170°C and recovers at around 150°C. |
| 2 | -VS | power_in | Negative power supply; the input common-mode range extends to V-, and supply span (+VS to -VS) is 4.5 V to 36 V with a 40 V absolute maximum. |
| 3 | +In | input | Noninverting input; the common-mode input range extends to V- and is specified up to (V+) - 1.5 V. |
| 4 | -In | input | Inverting input; input current is limited to ±10 mA absolute maximum. |
| 5 | +VS | power_in | Positive power supply; supply voltage range is 4.5 V to 36 V with a 40 V absolute maximum across (+VS) - (-VS). |
