TDA7803A High efficiency digital input automotive quad power amplifier with built-in diagnostics features, start stop compatible Datasheet - production data Programmable diagnostic pin CMOS compatible enable pin 0 03 Thermal protection PowerSO-36 Pop free in mute to play transitions and viceversa Flexiwatt 27 (SMD) Description The TDA7803A is a single chip quad bridge Flexiwatt 27 Flexiwatt 27 amplifier in advanced BCD technology (horizontal) (vertical) integrating: a full D/A converter, digital input for 2 direct connection to I S (or TDM) and powerful MOSFET output stages. Features The integrated D/A converter allows the AEC-Q100 qualified performance to reach an outstanding 115 dB S/N ratio with more than 110 dB of dynamic range. 24-bit digital processing Moreover the TDA7803A integrates an innovative 115 dB dynamic range (A-weighted) high efficiency concept, optimized also for SB-I (SB - improved) high efficiency operation uncorrelated music signals. The device is the highest non - class D efficiency designed to be compatible to battery modulation Parallel mode function availability for class-G systems. High output power capability: Thanks to this concept, the dissipated output 4 x 27 W 4 14.4 V, 1 kHz, THD = 10% power under average listening conditions can be reduced up to 50% when compared to the 4 x 47 W 2 14.4 V, 1 kHz, THD = 10% conventional class AB solutions. Flexible mode control: 2 The TDA7803A integrates also a programmable Full I C bus driving 1.8V/3.3V) with four PLL that is able to lock at the input frequencies of addresses selectable (only for PowerSO36 64*Fs for all the input configurations. package option) The device is equipped with a full diagnostics array Independent front/rear play/ mute that communicates the status of each speaker Selectable digital gains for very-low noise 2 2 through the I C bus. The same I C bus allows to line-out function control several configurations of the device. Digital diagnostic with DC and AC load The TDA7803A is able to play music down to 6 V detections supply voltage - so it is compatible with the so Start-stop compatibility (operation down to 6V) called start stop battery profile recently adopted Sample rates: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz by several car makers (thus reducing the fuel consumption and the impact over the Flexible serial data port (1.8 V / 3.3 V): 2 environment).
