3 Description

The TAS5830 is a stereo high-performance, closedloop

Class-D with integrated audio processor and up

to 192kHz audio support.

After startup with Software Control Mode, TAS5830

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 TAS5830 supports a delay buffer up

to 5ms in BTL mode or 10ms in PBTL mode, Class-

H control significantly helps to increase the system

efficiency.

When setting the device into Hardware control mode,

TAS5830 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.

The TAS5830 also provides the DSP features

Rattle suppression and Frequency limiter. Rattle

suppression reduces the gain of the signal at

frequencies that cause rattle through interaction with

the speaker enclosure, improving sound quality. The

frequency limiter process senses the input level, limits

the gain of EQ dynamically and helps SPL without

phase change.
