Description

The FAN7005 is a dual, fully differential audio power ampli-

fier 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 con-

sumption 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.
