Closed Loop I2S Input Amplifier with Power Limiter and Integrated Headphone, PVDDmax of 16.5V - TAS5760LD

TAS5760LD (ACTIVE)

Closed Loop I2S Input Amplifier with Power Limiter and Integrated Headphone, PVDDmax of 16.5V

Description

The TAS5760LD is a stereo I2S input device which includes hardware and software (I²C) control modes, integrated digital clipper, several gain options, and a wide power supply operating range to enable use in a multitude of applications. The TAS5760LD operates with a nominal supply voltage from 4.5 to 15 VDC. 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 120 mΩ RDS(ON) of the output MOSFETs. Additionally, a thermally enhanced 48-Pin TSSOP provides excellent operation in the elevated ambient temperatures found in modern consumer electronic devices.

The entire TAS5760xx family is pin to pin compatible in the 48-Pin TSSOP package. Alternatively, to achieve the smallest possible solutions size for applications where pin to pin compatibility and a headphone or line driver are not required, a 32-Pin TSSOP package is offered for the TAS5760M and TAS5760L devices. The I2C register map in all of the TAS5760xx family is identical, to ensure low development overhead when choosing between devices based upon system level requirements.
