DESCRIPTIONThe TDA7365 is a new technology Dual Audio Am-
plifier in Multiwatt15 package especially designed
for stereo car radio applications.
Thanks to the fully complementary output configu-
ration the TDA7365 delivers a rail to rail voltage
swing with no need of boostrap capacitors
It includes a solid state switch, enabled by a ST-BY
function common to the audio section, suitable for
supplying both the signal processing part of the car
radio set and the lamps. As a results the power-on
operation is simplified, thereby saving cost and
space in the whole power section.
