LA4629
Two-Channel Audio Frequency Power Amplifier
Overview
The LA4629 is a 2-channel power amplifier de-
veloped for use in radio/cassette player products.
The LA4629 reduces the number of required ex-
ternal components by 50% over earlier products
(BS/NF capacitors and oscillation prevention RC
components) and thus can contribute significantly
to space saving in end products.
