PT3300 普诚F类音频功率放大器
DESCRIPTION
The PT3300 is a Class-F audio power amplifier withhigh efficiency and high quality. It has two modes ofoperation, Class-D mode and Class-F(Class-AB)mode, so can avoid FM radio interference. Whenoperating with a 5V supply voltage, it is capable ofdriving a 4Ω speaker load at a continuous averageoutput of 3.2W with 10% THD+N. The externalapplication circuit is simple, integrated internalfeedback resistor, do without LC low-pass filter. ThePT3300 has HSOP8 (with heat sink) package, andhas low EMI. It is very suitable for small volume,convenient portable audio products with FM radio.Built-in over-temperature protection, package size isnot occupied PCB space. Meanwhile, the PT3300offers built-in and shut-down control circuitry foroptimal pop-free performance.
APPLICATIONS
● Portable speaker
● LCD TV or Monitor
● Laptop or MID
● Portable DVD
