Description
The TDA7803A is a single chip quad bridge
amplifier in advanced BCD technology
integrating: a full D/A converter, digital input for
direct connection to I2S (or TDM) and powerful
MOSFET output stages.
The integrated D/A converter allows the
performance to reach an outstanding 115 dB S/N
ratio with more than 110 dB of dynamic range.
Moreover the TDA7803A integrates an innovative
high efficiency concept, optimized also for
uncorrelated music signals. The device is
designed to be compatible to battery modulation
for class-G systems.
Thanks to this concept, the dissipated “output
power” under average listening conditions can be
reduced up to 50% when compared to the
conventional class AB solutions.
The TDA7803A integrates also a programmable
PLL that is able to lock at the input frequencies of
64*Fs for all the input configurations.
The device is equipped with a full diagnostics array
that communicates the status of each speaker
through the I2C bus. The same I2C bus allows to
control several configurations of the device.
The TDA7803A is able to play music down to 6 V
supply voltage - so it is compatible with the so
called 'start stop' battery profile recently adopted
by several car makers (thus reducing the fuel
consumption and the impact over the
environment).
