DescriptionThe FAN7021 is a bridge connected audio power amplifier
capable of delivering 1W of continuous average power to an
8Ω 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.
