3 Description
The TPA3250 device 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.
With a 32V power supply the device can drive up to 2
x 130 W peak into 4-
Ω load and 2 x 70 W continuous
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, TPA3250
achieves both high power efficiency and very low
power stage idle losses below 1 W. This is achieved
through the use of 60 m
Ω MOSFETs and an
optimized
gate
driver
scheme
that
achieves
significantly lower idle losses than typical discrete
implementations.
