产品概述

描述

The TDA7901 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 117 dB S/N ratio with more than 117 dB of dynamic range. Moreover the TDA7901 integrates an innovative high efficiency concept, optimized also for uncorrelated music signals. The device implements class G operation mode.

Thanks to this concept, the dissipated “output power” under average listening conditions can be reduced more than the standard class AB devices. The TDA7901 also integrates 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 and advanced diagnostics array that communicates the status of each speaker through the I2C bus. DIM (Digital-Impedance-Meter) function allows to measure the value of the load. The same I2C bus allows to control several configurations of the device.

The TDA7901 is able to play music down to 4.5 V supply voltage thus it is compatible with the so-called 'start stop' battery profile. Several car makers adopt 'Start stop' feature to reduce the fuel consumption and the impact over the environment.

Moreover, TDA7901 guarantees EMI outstanding performance, in line with the CISPR25-restrictive standard requirement.
