The CS4270 is a stereo audio codec with single-ended inputs and outputs, and a dynamic range of 105 dB and THD+N of -95 dB. Requiring a minimal set of passive external components, the CS4270 provides designers with a simple solution that reduces the bill-of-materials cost and the required space on their printed circuit board. Configuring the IC through an industry standard control port provides access to additional features such as logarithmic digital volume control. The CS4270 utilizes Popguard® technology for controlling clicks and pops associated with power cycling, which eliminates external mute control circuitry.
