„ General Description
The AP4809 is a stereo power amplifier in an 8-pin
SOP package capable of delivering 70mW
continuous average power per channel into 32Ω
loads with less than 0.1% (THD+N) from a 5V power
supply. Amplifier gain is externally configured by
means of two resistors per input channel. It was
designed specially to provide high quality output
power with a minimal amount of external
components and is therefore optimally suited for
low-power portable systems.
