Description

The 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.
