DESCRIPTION
The TAS5110A is a high-performance true-digital audio
amplifier (TDAA) power stage, designed to drive 50 W per
channel. The TAS5110A incorporates TI’s Equibit and
PurePath Digital 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 TAS5110A 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.
Overcurrent protection, overtemperature, and
undervoltage protections are built into the TAS5110A,
safeguarding the H-bridge and speakers against output
shorts, overvoltage conditions, and other fault conditions
that could damage the system.
