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.
