TDA7802

TDA7802 High efficiency digital input quad power amplifier with built-in diagnostics features, start stop compatible Data brief Description The TDA7802 is a single chip quad bridge amplifier in advanced BCD technology 0 03 integrating: a full D/A converter, digital input for Flexiwatt27 Flexiwatt27 (SMD) PowerSO36 2 direct connection to I S (or TDM) and powerful MOSFET output stages. Features The integrated D/A converter allows the performance to reach an outstanding 115 dB S/N 24-bit resolution ratio with more than 110 dB of dynamic range. 110 dB dynamic range (A-weighted) Moreover the TDA7802 integrates an innovative SB-I (SB - improved) high efficiency operation high efficiency concept, optimized also for the highest non - class D efficiency uncorrelated music signals, that makes it the most suitable device to simplify the thermal 1 Ohm driving capability (only in PowerSO36 management in high power sets. package) High output power capability: Thanks to this concept, the dissipated output 4 x 28 W 4 14.4 V, 1 kHz, THD = 10 % power under average listening conditions can be reduced up to 50% when compared to the Max output power: 4 x 72 W 2 conventional class AB solutions. Flexible mode control: 2 The TDA7802 integrates also a programmable Full I C bus driving 1.8 V/3.3 V) with four PLL that is able to lock at the input frequencies of addresses selectable (only for PowerSO36 64*Fs and 50*Fs for all the input configurations. package option) The device is equipped with a full diagnostics Independent front/rear play/ mute array that communicates the status of each Four selectable gains for very-low noise 2 2 speaker through the I C bus. The same I C bus line-out function allows to control several configurations of the Digital diagnostic with DC and AC load device. detections The TDA7802 is able to play music down to 6 V 2 Optional H/W control (no I C bus) supply voltage - so it is compatible with the so Start-stop compatibility (operation down to 6 V) called start stop battery profile recently adopted by several car makers (thus reducing the fuel Sample rates: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz consumption and and the impact over the Flexible serial data port (1.8 V / 3.3 V): environment). 2 I S standard, TDM 4Ch, TDM 8Ch, TDM 16Ch Table 1.
