DESCRIPTION
The TAS5615 is a high-performance analog input
CLass D amplifier with integrated closed loop
feedback technology (known as PurePath™ HD). It
has the ability to drive up to 160 W⁽¹⁾ Stereo into 8Ω
speakers from a single 50V supply.
PurePath™ HD technology enables traditional
AB-Amplifier performance (<0.03% THD) levels while
providing the power efficiency of traditional class D
amplifiers.
Ultra Low 0.03% THD+N is flat across all frequencies,
ensuring that the amplifier doesn’t 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.

(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
heatslug and the heat sink should be used to achieve high
output power levels
