PT3300 Datasheet (PTC) - 3.2W Class-F Audio Power Amplifier

PT3300, 3.2W Class-F Audio Power Amplifier

The PT3300 is a Class-F audio power amplifier with high efficiency and high quality.

It has two modes of operation, Class-D mode and Class-F(Class-AB) mode, so can avoid FM radio interference.

When operating with a 5V supply voltage, it is capable of driving a 4Ω speaker load at a continuous average
