3D Model

The CS4270  is a high-performance, integrated audio CODEC. The CS4270  performs stereo analogue-to-digital (A/D) and digital-to-analog (D/A) conversion of up to 24-bit serial values at sample rates up to 216  kHz. Standard 50/15  µs de-emphasis is available for sampling rates of 44.1 kHz for compatibility with digital audio programs mastered using the 50/15  µs pre-emphasis technique.
Integrated level translators allow easy interfacing between the CS4270  and other devices operating over a wide range of logic levels.
Independently addressable high-pass filters are available for the right and left channels of the A/D. This allows the A/D  to be used in a wide variety of applications where one audio channel and one DC measurement channel is desired.
The CS4270  is available in a 24-pin TSSOP package in both Commercial (-10° to +70° C) and Automotive grades (-40° to +85  ° C). The CDB4270  Customer Demonstration board is also available for device evaluation and implementation suggestions. Please refer to “Ordering Information” on page 47  for complete ordering information.
