DESCRIPTION
The TAS5616 is a high-performance PWM-input
class-D amplifier with integrated closed-loop
feedback technology (known as PurePath™ HD
technology). It has the ability to drive up to 160-W
(1) _{stereo into 8-Ω speakers from a single 50-V}
supply.
PurePath™ HD technology enables traditional
AB-amplifier performance (<0.03% THD) levels while
providing the power efficiency of traditional class-D
amplifiers.
Ultralow 0.03% THD+N is flat across all frequencies,
ensuring that the amplifier does not add uneven
distortion characteristics, and helps maintain a natural
sound.
The efficiency of this class-D amplifier is greater than
90%. Undervoltage protection, overtemperature,
clipping, short-circuit and overcurrent protection are
all integrated, safeguarding the device and speakers
against fault conditions that could damage the
system. PurePath HD™

(1) Achievable output power levels are dependent on the thermal
configuration of the target application. A high performance
thermal interface material between the package exposed
thermal pad and the heat sink should be used to achieve high
output power levels.
