DESCRIPTION
The TAS5101 is a high-performance true digital stereo
audio amplifier (TDAA) Power Stage, designed to drive
2
× 15 watts per channel. The TAS5101 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 TAS5101 accepts a stereo
PWM 3.3V 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 TAS5101,
safeguarding the H-bridge and speakers against output
shorts,
over-voltage
conditions,
and
other
fault
conditions that could damage the system.
