Preliminary Data
Features
Input stage and gain compressor Over-modulation protection and current limiting Modulator DAC Step-up Mode control Diagnostics / safety Power control 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.
