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.
