Audio Amplifier ICs

There are many types of power amplifer chips, ranging from 1w to 64W. The power ampliher chipscurrently promoted are all debugged with our voice chips, and have the highest sound quality matching.

Waytronic audio amplifier IC incorporates built-in overcurrent protection, short circuit protection, and overheating protection.

The operating temperature range of the chip can reach -40-85℃

It has been widely used in home audio, security alarm equipment, smart home, broadcasting systems, children’s toys, and other equipment.

High-power Voice Chip

Compared with traditional playback voice chips, the main adjustment is to adjust the outputcircuit. The voice chip can output a power of up to 3W without the need for an additional poweramplifer chip to directly drive an 8R3W speaker. Two series have been launched,WTN6040FP-14S and WT588F02BP-14S. They are 40 seconds and 170 seconds of voice respectively. Both chips can repeatedly erase and replace the internal voice fles of the chip through theprogrammer.
