  • TDA7808 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 TDA7808 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.
    TDA7808 integrates also a programmable PLL that is able to lock at the input frequencies of 64*Fs for all the input configurations.
    TDA7808 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 car makers (thus reducing the fuel consumption and the impact over the environment).
