TAS5110A 50-W DIGITAL AMPLIFIER POWER STAGE
FEATURES DESCRIPTION 50 W RMS Power Into 6 Ω at 10% THD
The TAS5110A is a high-performance true-digital audio
40 W RMS Power Into 6 Ω at 0.1% THD amplifier (TDAA) power stage, designed to drive 50 W per THD+N < 0.09% Typical (1-k Hz Input Signal) channel. The TAS5110A incorporates TI’s Equibit and
93-d B Dynamic Range (TDAA System) Pure Path Digital technology and is used in conjunction Power Efficiency > 90% Into 6-Ω and 8-Ω with a digital audio PWM processor (TAS50xx) to deliver Load high-power, true-digital audio amplification. The efficiency of this digital amplifier can be greater than 90%, reducing
