The CS35L45 is a 55 nm smart boosted amplifier solution with an integrated DSP that drives the very loudest audio without compromising sound quality in mobile devices. The hardware platform of this flagship audio IC is designed as a mono 6.8 W boosted Class D amplifier with the lowest noise and quiescent power consumption of any amplifier in its class. Also on board is a digitally controlled Class H tracking inductive boost converter capable of boosting battery voltages up to 15 V for speaker playback. The chip includes voltage and current sensing feedback at the speaker output and the battery to improve the accuracy of integrated algorithms.
