Packing two analog-to-digital and six digital-to-analog channels, the CS42406 surroundsound codec simplifies system design by providing single-ended inputs and outputs.
Developed by Cirrus Logic Inc., the codec offers high-quality 24-bit conversion. The digital-to-analog converters (DACs) deliver a dynamic range of 102 dB, and the analog-to-digital converter (ADC) provides 105 dB. The company's Popguard technology, also incorporated in the codec, reduces overall system cost by eliminating the filtering components needed to block the "clicks and pops" that often occur when powering single-ended-output DACs on and off.
The CS42406 is the first member of a surroundsound codec family that includes the CS42416, CS42418, CS42426, and CS42428. Family members will differ in dynamic range and I/O options. Prices range from $2.62 for the CS42406 to $6.35 apiece in lots of 10,000 units. For more, go to www.cirrus.com.
