The TAS5110A is a high-performance 50-W digital amplifier chip from TI. It uses TI's proprietary PurePath Digital technology and has an efficiency of over 90%. It can be used in DVD receivers, home theaters, mini/micro component systems, internet music devices, and car audio amplifiers.
The TAS5110A is a high-performance true-digital audio amplifier (TDAA) power stage designed to drive 50 W per channel. It incorporates Texas Instruments' Equibit and PurePath Digital technology and is used in conjunction with a digital audio PWM processor to deliver high-power, true-digital audio amplification. The device accepts a mono PWM 3.3-V input and controls the switching of an internal CMOS H-bridge.
