Description

The TDA7802 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 TDA7802 integrates an innovative

high efficiency concept, optimized also for

uncorrelated music signals, that makes it the most

suitable device to simplify the thermal

management in high power sets.

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 TDA7802 integrates also a programmable

PLL that is able to lock at the input frequencies of

64*Fs and 50*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 TDA7802 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 and the impact over the

environment).
