Description

The FAN7023 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 FAN7023 requires few external components and

operates on low supply voltage from 2.2V to 5.5V. Since the

FAN7023 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 FAN7023 features an externally

controlled gain, low power consumption shutdown mode

(0.01uA,typ.). Additional FAN7023 features include thermal

shutdown protection, unity gain stability, and external gain

set.
