TAS5760MDAPR Digital power Amplifier Chip - An efficient digital audio solution

Overview

The TAS5760M is a stereo I2S input device featuring both hardware and software (I²C) control modes, an integrated digital clipper, multiple gain options, and a wide power supply operating range, making it suitable for a variety of renderings. The nominal operating power supply voltage of TAS5760M is 4.5V to 24V DC. The 120mΩRDS(ON) of the output MOSFET takes into account both heat dissipation performance and device cost, complementing each other. In addition, the thermally enhanced 48-pin TSSOP package can perform exceptionally well at higher ambient temperatures in modern consumer electronic devices. The entire TAS5760xx series adopts a 48-Pin TSSOP package, and all member devices of the series are pin-to-pin compatible with each other. In addition, for applications that may not require headphone/line drivers and do not demand pin-to-pin compatibility but wish to minimize the solution, the TAS5760M and TAS5760L devices can be packaged in a 32-pin thin form factor (TSSOP) package. The I2C register mapping of all devices in the TAS5760xx series is the same. As a result, when devices need to be replaced according to system-level requirements, the workload of secondary development can be reduced.
