Overview
The LA4802T is a headphone stereo power amplifier for
portable CD and MD players. It features a high signal-to-
noise ratio, a high ripple rejection ratio, low distortion,
and low current drain.
Functions
Headphone stereo power amplifier
Power switch
Muting switch
Beep tone function control input pin (The beep tone
function can be used regardless of whether the mute
function is on or off.)
Features
High signal-to-noise ratio (100 dB typical at 7.5 μV)
High ripple rejection ratio (70 dB typical)
Low current drain (950 μA typical)
On-chip bass compensation circuit
(Compensates for bass frequency attenuation due to the
output capacitors and achieves flat frequency
characteristics.)
