The CS42L52 is a 24-bit low-power stereo audio codec noted for its high levels of integration and high-performance audio output. Providing up to one watt-per-channel of highly efficient Class D amplification to external speakers, or enough power to drive 44 milliwatts per channel into stereo headphones, 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. This IC is ideal for portable consumer electronics applications such as portable media players, game devices, MP3 player accessories, IC recorders, digital cameras and camcorders.
The CS42L52 builds upon the innovative design techniques of Cirrus Logic’s recently introduced low-power audio codecs by creating its own on-chip negative power supply voltage. 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. The elimination of these capacitors reduces costs, simplifies product designs and enables smaller product form factors. The codec also features enhanced master clock support, which includes standard audio frequencies, as well as USB and video clocks.
The CS42L52 utilizes a 40-pin QFN package and consumes only 13 milliwatts of power at 1.8 volts in playback mode while driving stereo headphones.
