675mW CMOS Mono Power Amplifier with
Shutdown
Description
The FAN7024 is a bridge connected audio power amplifier
capable of delivering 675mW of continuous average power
to an 8鈩?load with less than 0.3%(THD) from a 5V power
supply. The FAN7024 requires few external components and
operates on low supply voltage from 2.3V to 5.5V. Since the
FAN7024 does not require output coupling capacitors,
bootstrap capacitors, or snubber networks, it is ideally suited
for low power portable systems that require minimum
volume and weight. The FAN7024 features an externally
controlled gain and low power consumption shutdown mode
(0.1uA,typ.). Additional FAN7024 features include thermal
shutdown protection, unity gain stability, and external gain
set.
