The FAN7024 requires few external components and operates on low supply voltage from 2.3V to 5.5V. Since the FAN7024 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 FAN7024 features an externally controlled gain and low power consumption shutdown mode (0.1uA,typ.). Additional FAN7024 features include thermal shutdown protection, unity gain stability, and external gain set. 8MSOP 1 Continuous Average Power is 675mW (8Ω) Low THD: Typical 0.3% @ Po=500mW PSRR@217Hz, Input Terminated : 60dB Do Not Need Output Coupling Capacitor or Bootstrap Capacitor Low Shutdown Current: Typical 0.1µA Shutdown: High Active Click & Pop Suppression circuitry Built in TSD Circuit Typical Applications • Cellular Phone • PDA • Portable Audio Systems 10MLP 1 BOTTOM VIEW Internal Block Diagram 4 3 IN- VO1 5 IN+ 20KΩ 20KΩ 2 BP 100KΩ VDD/2 8 VO2 6 VDD BIAS & Shutdown 100KΩ 1 SD 7 GND Rev. 1.0.0 ©2003 Fairchild Semiconductor Corporation FAN7024 Pin Assignments VO2 GND VDD VO1 8 7 6 5 VO2 NC VDD NC 10 9 8 7 6 1 2 3 4 5 024 YWW 1 SD 2 BP 3 IN+ 4 IN- SD BP GND IN+ IN- VO1 8MSOP 10MLP(BOTTOM VIEW) Pin Definitions Pin Number 1(1) 2(2) 3(4) 4(5) 5(6) 6(8) 7(3) 8(10) Pin Name SD BP IN+ INVO1 VDD GND VO2 Pin Function Description ( ) : 10MLP Shutdown.
