LA4802T
Headphone Stereo Power Amplifier
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.)
• Ultraminiature package (MSOP-20)
