DESCRIPTION
TheTDA7365is a newtechnologyDual Audio Amplifier in Multiwatt15 package especially designed
forstereo car radio applications.
Thanksto the fully complementaryoutput configuration the TDA7365 delivers a rail to rail voltage
swingwith no needof boostrapcapacitors
It includesa solidstateswitch,enabledby a ST-BY
function common to the audio section, suitable for
supplyingboth the signalprocessingpart of the car
radioset and the lamps. As a resultsthe power-on
operation is simplified, thereby saving cost and
space inthewhole powersection.
