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 dynamic range compression (DRC) function. The device can operate from a wide PVDD power supply range to enable use in numerous applications. The TAS5729MD operates with a nominal supply voltage from 4.5 to 24 VDC. The device is controlled by an I²C control port. The device has an integrated DirectPath™ headphone amplifier and 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-mΩ RDS(ON) of the output MOSFETs. Additionally, a thermally enhanced HTSSOP 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 the entire TAS5729xx family is identical to ensure low development overhead to choose between devices based upon system level requirements.
