These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

DESCRIPTION

The TAS5729MD is a stereo I²S input device which includes a digital auto processor with two-band automatic

gain limiting (AGL), digital equalization, course and fine volume control, and PWM Level meter. The AGL is an

enhanced dymanic range compression (DRC) function. The device can operate from a wide PVDD power supply

range to enable use in a multitude of applications. The TAS5729MD operates with a nominal supply voltage from

4.5 to 24 VDC. It is controlled by an (I²C) control port.The device has an integrated DirectPath™ headphone

amplifier / line driver to increase system level integration and reduce total solution costs.

An optimal mix of thermal performance and device cost is provided in the 200 m

Ω RDS(ON) of the output

MOSFETs. Additionally, a thermally enhanced 48-Pin TSSOP provides excellent operation in the elevated

ambient temperatures found in today's modern consumer electronic devices.

The entire TAS5729xx family is pin to pin compatible allowing a single hardware solution to be used across

several end application platforms. Additionally, the I²C register map in all of the TAS5729xx family is identical, to

ensure low development overhead to choose between devices based upon system level requirements.
