3 Description
The TAS5827 is a stereo high-performance, closedloop
Class-D with integrated audio processor and up
to 192-kHz audio support.
After startup with Software Control Mode, TAS5827
not only implements classic BQs, 3-Band DRC, AGL,
but also proprietary audio envelope tracking Class-H
control algorithm. The Class-H algorithm detects the
required audio power demand and provides a PWM
format control signal to the DC-DC converter via the
GPIO pin. The TAS5827 supports a delay buffer up
to 5 ms in BTL mode or 10 ms in PBTL mode, Class-
H control significantly helps to increase the system
efficiency.
When setting the device into Hardware control mode,
TAS5827 supports selecting switching frequency,
analog gain, BTL/PBTL mode and cycle by cycle
current limit threshold through pin configuration. This
mode is designed to eliminate end system software
driver integration efforts.
