FAN7005

www.fairchildsemi.com FAN7005 200mW Stereo Power Amplifier with Shutdown Features 200mW and 300mW Power Per Each Channel into 8Ω Load with Less Than 0.3% and 10% THD+N, Respectively Low Shutdown Current : 0.1µA(Typ.) No Bootstrap Capacitors or Snubber Circuits are Necessary Stable Unity-Gain Guaranteed Stability Under No Load Condition External Gain Configuration Capability Thermal Shutdown Protection Circuitry Pop Reduction Circuit 8MSOP Surface Mount Packaging Description The FAN7005 is a dual, fully differential audio power amplifier delivering 200mW(typ.) of continuous power into an 8Ω load. When driving 200mW into an 8Ω load from a 5V power supply, the FAN7005 has less than 0.3% of THD+N over the entire audible frequency range. To reduce the power consumption in portable applications, the FAN7005 provides a shutdown capability. In shutdown condition, current consumption is reduced to less than 2µA. The FAN7005 is designed specifically to provide high quality output power with a minimal amount of external components using surface mount packaging. Since the additional snubber circuits or bootstrap capacitors are not needed, the FAN7005 is well suited for portable systems and other hand-held devices.
