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 equibitt
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.
