The CS4270 stereo audio codec utilizes a mulitbit Delta-Sigma architecture, which provides high-quality analog-to-digital and digital-to-analog data conversion with 24-bit resolution at any standard digital audio sampling rate up to 216 kHz. Ideal for applications such as set-top boxes, DVD recorders, audio/video receivers, digital televisions, effects processors, musical instruments and automotive audio applications, the CS4270 complements an already strong codec product offering from Cirrus Logic. The CS4270 employs single-ended inputs and outputs and achieves 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 required space on their printed circuit board. The CS4270 can operate from a single 3.3 V or 5 V power supply and includes on-chip-level shifters for direct interface to logic levels from 1.8 V to 5.0 V. Basic functionality is available by simply configuring the pins in hardware mode. Configuring the device through an industry standard control port can access additional features such as logarithmic digital volume control. As with other Cirrus Logic single-ended output data converters, the CS4270 utilizes Popguard® technology for controlling clicks and pops associated with power cycling, which eliminates external mute control circuitry.
