Datasheet Summary
High Power Stereo Class-D Audio Power Amplifier with Adjustable Power Limit & Automatic Level Control
GENERAL DESCRIPTION
The ft3128 is a high power, high efficiency, stereo Class-D audio power amplifier with adjustable power limit (APL) and automatic level control (ALC). It operates with a wide range of supply voltages from 5.5V to 20V. With 15V supply voltage, it can deliver into a pair of 4Ω speakers an output power of 22W per channel with 1% THD+N, or an ALC output power of 20W per channel with 0.5% THD+N.
The high efficiency (up to 90%) of ft3128 extends battery life in playing music and allows it to deliver an output power of 2X20W without the need for a bulky heat sink on a...
