Description

The FAN7024 is a bridge connected audio power amplifier

capable of delivering 675mW of continuous average power

to an 8Ω 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.
