TP5531U-CR

3PEAK · Operational Amplifier · SC-70-5

TP5531U-CR from 3PEAK, in a SC-70-5. 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 +IN input Non-inverting input of the amplifier. Rail-to-rail input range from -Vs to +Vs.
2 -Vs power_in Negative power supply. Normally tied to GND. May be tied to a voltage other than GND provided (+Vs) - (-Vs) is 1.8 V to 5.5 V. Bypass with a 0.1 µF capacitor as close to the part as possible when not connected to GND.
3 -IN input Inverting input of the amplifier. Rail-to-rail input range from -Vs to +Vs.
4 OUT output Amplifier output. The voltage range extends to within millivolts of each supply rail (rail-to-rail output).
5 +Vs power_in Positive power supply. Typical range 1.8 V to 5.5 V (single or split supply, provided (+Vs) - (-Vs) is between 1.8 V and 5.5 V). Bypass with a 0.1 µF capacitor between supply pins or from supply to GND as close to the part as possible.
