CS42L52 Overview
The CS42L52 is a 24-bit, low-power stereo audio codec providing up to 1 W per channel of highly efficient Class D amplification to external speakers, or enough power to drive 44 mW per channel into stereo headphones and consumes only 13 mW of power at 1.8 V in playback mode. The CS42L52 offers the flexibility to run its core from a single power supply and directly connect the Class D amplifier to the battery supply for a more efficient operation. With its ground-centered outputs, the CS42L52 helps to reduce clicks and pops during start up, improves low-end frequency response and eliminates costly, space-consuming DC blocking capacitors.
