Texas Instruments TAS5760M/TAS5760M-Q1 I2S Input Class-D Amplifier

Texas Instruments TAS5760M/TAS5760M-Q1 I2S Input Amplifier is a stereo I2S input device that includes hardware and software (I2C) control modes and an integrated digital clipper. The device also includes several gain options and a wide power supply operating range to enable use in many applications. The TAS5760M operates with a nominal supply voltage from 4.5 to 24VDC. An optimal mix of thermal performance and device cost is provided in the 120mΩ 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 TAS5760M-Q1 devices are AEC-Q100 qualified for automotive applications.
