www.fairchildsemi.com FAN7023 1W CMOS Mono Power Amplifier Features Description • Continuous Average Power is 1.0W (8?) The FAN7023 is a bridge connected audio power amplifier • Low THD: Typical 0.2% @ 1kHz (5V) capable of delivering 1W of continuous average power to an • Do Not Need Output Coupling Capacitor or Bootstrap 8? load with less than 0.2%(THD) from a 5V power supply. Capacitor The FAN7023 requires few external components and • Low Shutdown Current: Typical 0.01µA operates on low supply voltage from 2.2V to 5.5V. Since the • Shutdown: High Active FAN7023 does not require output coupling capacitors, • Built in TSD Circuit bootstrap capacitors, or snubber networks, it is ideally suited for low power portable systems that require minimum volume and weight.
