DESCRIPTION

The TAS5110 is a high-performance true digital audio

amplifier (TDAA) power stage, designed to drive 50 W

per channel. The TAS5110 incorporates TI’s equibit

t

technology and is used in conjunction with a digital

audio PWM processor (TAS50xx) to deliver high-power,

true digital audio amplification. The efficiency of this

digital amplifier can be greater than 90%, reducing the

size of both the power supplies and heat sinks needed.

The TAS5110 accepts a mono PWM 3.3-V input and

controls the switching of an internal CMOS H-bridge.

When used with the TAS50xx PWM processor, system

performance of less than 0.09% THD is attainable.

Over-current

protection,

over-temperature,

and

under-voltage protections are built into the TAS5110,

safeguarding the H-bridge and speakers against output

shorts,

over-voltage

conditions,

and

other

fault

conditions that could damage the system.
