TP5531-TR

3PEAK · Operational Amplifier · SOT-23-5

TP5531-TR from 3PEAK, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 OUT output Amplifier output. Rail-to-rail output swings to within ~5mV (typ) / 10mV (max) of each supply rail with RL=10kΩ. Short-circuit current ±60mA; drives capacitive loads up to 1000pF.
2 V- power_in Negative power supply (−Vs). Typically tied to ground for single-supply operation. Total supply voltage (V+ minus V−) must be 1.8V to 5.5V. If not tied to ground, bypass with 0.1μF close to the pin.
3 +IN input Non-inverting input of the amplifier. Rail-to-rail common-mode range extends 100mV (typ) beyond each supply rail. Input bias current ±50pA typ (±200pA max). Protected by ESD diodes to each supply - limit input current to ≤10mA if driven beyond rails.
4 -IN input Inverting input of the amplifier. Rail-to-rail common-mode range extends 100mV (typ) beyond each supply rail. Input bias current ±50pA typ. Protected by ESD diodes to each supply - limit input current to ≤10mA if driven beyond rails.
5 V+ power_in Positive power supply (+Vs). Typically 1.8V to 5.5V. Total supply voltage (V+ minus V−) must be 1.8V to 5.5V. Bypass with a 0.1μF capacitor as close to the pin as possible. Absolute maximum supply voltage: 6V.
