Internal Block Diagram
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.
