TPA1881-TR

3PEAK · Operational Amplifier · SOT-23-5

TPA1881-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 Output swings rail-to-rail, and the datasheet states a short-circuit duration of infinite (a heat sink may be needed to keep junction temperature below the absolute maximum).
2 -Vs power_in Negative supply rail; the input common-mode range extends to V-, and total supply (+VS) - (-VS) is 4.5 V to 36 V with an absolute maximum of 40 V.
3 +In input Non-inverting input; if the input is driven more than 300 mV beyond the negative supply, the input current must be limited to less than 10 mA.
4 -In input Inverting input; if the input is driven more than 300 mV beyond the negative supply, the input current must be limited to less than 10 mA.
5 +Vs power_in Positive supply rail; supply range is 4.5 V to 36 V with an absolute maximum of 40 V.
