SLOS982C August 2017 – April 2018 TAS5755M
PRODUCTION DATA.
The TAS5755M is an efficient 50-W stereo I2S input Class-D audio power amplifier. The digital auto processor of the device uses noise shaping and customized correction algorithms to achieve a great power efficiency and high audio performance. Also, the device has up to eight Equalizers per channel and two -band configurable Dynamic Range Control (DRC).
The device needs only a single DVDD supply in addition to the higher-voltage PVDD power supply. An internal voltage regulator provides suitable voltage levels for the gate drive circuit. The wide PVDD power supply range of the device enables its use in a multitude of applications.
The TAS5755M is a slave-only device that is controlled by a bidirectional I2C interface that supports both 100-kHz and 400-kHz data transfer rates for single- and multiple-byte write and read operations. This control interface is used to program the registers of the device and read the device status.
The PWM of this device operates with a carrier frequency between 384 kHz and 354 kHz, depending the sampling rate. This device allows the use of the same clock signal for both MCLK and BCLK (64xFs) when using a sampling frequency of 44.1 kHz or 48 kHz.
This device can be used in three different modes of operation, Stereo BTL mode, Single filter PBTL mono mode, and 2.1 mode.
