Datasheet Summary
PT3300 3.2W Class-F Audio Power Amplifier
DESCRIPTION
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 output of 3.2W with 10% THD+N. The external application circuit is simple, integrated internal feedback resistor, do without LC low-pass filter. The PT3300 has HSOP8 (with heat sink) package, and has low EMI. It is very suitable for small volume, convenient portable audio products with FM radio. Built-in over-temperature protection, package...
