PT3300 - 3.2W Class-F Audio Power Amplifier

General 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.

Key Features

  • CMOS technology.
  • Supply Voltage(VDD) from 2.5V to 5.0V.
  • Avoid FM radio interference.
  • Maximum output power:3.2W (VDD=5V, RL=4Ω, THD=10%).
  • Integrated low-pass filter for out-of-band noise rejection.
  • Gv can be adjusted by adjusting the input resistance.
  • Shutdown function, turn on can into save mode.
  • Built-in pop and click noise suppress.
  • Built-in over-temperature protection.
  • Available in HSOP8 package.

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 size is not occupied PCB space.
