Features
! Six 24-bit D/A, two 24-bit A/D Converters ! 114 dB DAC / 114 dB ADC Dynamic Range ! -100 dB THD+N ! System Sampling Rates up to 192 kHz ! Integrated Low-Jitter PLL for Increased System
General Description
The CS42426 codec provides two analog-to-digital and six digital-to-analog delta-sigma converters, as well as an integrated PLL. The CS42426 integrated PLL provides a low-jitter system clock. The internal stereo ADC is capable of independent channel gain control for single-ended or differential analog inputs. All six channels of DAC provide digital volume control and differential analog outputs. The general-purpose outputs may be driven high or low, or mapped to a variety of DAC mute controls or ADC overflow indicators. The CS42426 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise, such as A/V receivers, DVD receivers, digital speaker and automotive audio systems. The CS42426 is available in a 64-pin LQFP package in both Commercial (-10° to +70° C) and Automotive (-40° to +85° C) grades. The CDB42428 Customer Demonstration board is also available for device evaluation. Refer to “Ordering Information” on page 71.
