TP1281L1-TR

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).
