TAS5760MD - Closed Loop I2S Input Amplifier with Power Limiter and Integrated Headphone, PVDDmax of 26.4V

The TAS5760MD is a stereo I2S input device which includes hardware andsoftware (I²C) control modes, integrateddigital clipper, severalgain options, and a wide power supply operating range to enable use in a multitude of applications.The TAS5760MD operates with a nominal supply voltage from 4.5 to24 VDC. The device has an integrated DirectPath™headphone amplifier and line driver to increase system level integration and reduce total solutioncosts.

An optimal mix of thermal performance and device cost is provided in the120-mΩ R_DS(ON) of the output MOSFETs. Additionally, athermally enhanced 48-Pin TSSOP provides excellent operation in the elevated ambienttemperatures found in modern consumer electronic devices.

The entire TAS5760xx family is pin-to-pin compatible in the 48-Pin TSSOPpackage. Alternatively,to achieve the smallest possible solutions size for applications where pin-to-pin compatibility anda headphone or line driver are not required, a 32-Pin TSSOP package is offered for the TAS5760M andTAS5760L devices. The I²C register map in all of the TAS5760xx devicesare identical, to ensure low development overhead when choosing between devices based uponsystem-level requirements.
