FAN7023

www.fairchildsemi.com FAN7023 Features 1W CMOS Mono Power Amplifier 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. 8-MSOP 10-MLP 1 BOTTOM VIEW Continuous Average Power is 1.0W (8Ω) Low THD: Typical 0.2% @ 1kHz (5V) Do Not Need Output Coupling Capacitor or Bootstrap Capacitor Low Shutdown Current: Typical 0.01µA Shutdown: High Active Built in TSD Circuit Typical Applications Cellular Phone PDA Portable Audio Systems 1 8-SOP 1 Internal Block Diagram 4 3 IN- VO1 5 IN+ 20kΩ 2 BP 100kΩ 6 VDD BIAS 100kΩ VDD/2 VO2 8 20kΩ 1 SD GND 7 Rev. 1.1.0 ©2003 Fairchild Semiconductor Corporation FAN7023 Pin Assignments VO2 8 GND 7 VDD 6 VO1 5 VO2 10 9 8 7 6 1 2 3 4 5 SD BP GND IN+ IN- FAN7021 FAN7023 NC VDD NC VO1 1 SD 2 BP 3 IN+ 4 IN- 10-MLP(BOTTOM VIEW) Pin Definitions Pin Number 1(1) 2(2) 3(4) 4(5) 5(6) 6(8) 7(...
