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.
