■ Modulator

■ DAC

■ Step-up

■ Mode control

■ Diagnostics / safety

■ Power control

Description

TDA7572 is a highly integrated, highly versatile,

semi-custom IC switch mode audio amplifier. It

integrates audio signal processing and power

amplification tailored for standalone remote bass

box applications, while providing versatility for full

bandwidth operation in either automotive or

consumer audio environments. It's configured as

one full bridge channel, using two clocked PWM

modulators driving external, complementary

FET's.

Broad operating voltage is supported, allowing

operation from both 14V and 42V automotive

power buses, as well as from split supplies for

consumer electronics use.

A current mode control boost converter controller

is provided to allow high power operation in a 14V

environment. Turn-on and turn-off transients are

minimized by soft muting/unmuting and careful

control of offsets within the IC.

Digital Audio input is supported by an integrated

one channel DAC. Sophisticated diagnostics and

protection provide fault reporting via I2C and

power shutdown for safety related faults.

TDA7572 is packaged in a HiQUAD-64 package.
