FAN7021

Features

CMOS Power Amplifier

Description

The FAN7021 is a bridge connected audio power amplifier

capable of delivering 1W of continuous average power to an

8鈩?load with less than 0.2%(THD) from a 5V power supply.

The FAN7021 require few external components and operate

on low supply voltage from 2.0V to 5.5V. Since the

FAN7021 does not require output coupling capacitor,

bootstrap capacitors, or snubber networks, it is ideally suited

for low power portable systems that require minimum

volume and weight. The FAN7021 feqtures an externally

controlled, low power consumption shutdown mode (0.01

uA,typ). Additional FAN7021 features include thermal

shutdown protection, unity gain stability, and external gain

set.
