Description
TPA3255 is a high
performance class-D power amplifier that enables true premium sound quality with
class-D efficiency.
It features an
advanced integrated feedback design and proprietary high-speed gate driver
error correction (PurePath™ Ultra-HD).
This technology
allows ultra low distortion across the audio band and superior audio quality.
The device is operated in AD-mode,
and can drive up
to 2 x 315 W into 4-Ω load at 10% THD
and 2 x 150 W unclipped into 8-Ω load and features a 2 VRMS analog input
interface that
works seamlessly with high performance DACs such as TI’s PCM5242. In addition
to excellent audio performance, TPA3255
achieves both high
power efficiency and very low power stage idle losses below 2.5W. This is
achieved through the use of 85 mΩ MOSFETs
and an optimized
gate driver scheme that achieves significantly lower idle losses than typical
discrete implementations.

Input method: analog and Bluetooth input function. When two modes are
input at the same time, the Bluetooth input is prioritized. After the Bluetooth
connection,
the RCA input is automatically disconnected; when the analog input is
required, please turn off the Bluetooth function of the mobile phone to switch.
