PT3371 Datasheet (PTC) - 3W Class-AB Audio Power Amplifier

PT3371, 3W Class-AB Audio Power Amplifier

The PT3371 is a Class-AB audio power amplifier.

When operating with a 5V supply voltage, it is capable of driving a 4Ω speaker load at a continuous average output of 3W with 10% THD+N.

The external application circuit is simple, integrated internal feedback resistor, do without LC low-pass filter.
