The CS4272 is a high-performance integrated audio codec that performs stereo analog-to-digital and digital/analog conversion of up to 24-bit serial values at sample rates up to 192 kHz. The CS4272 utilizes a differential analog architecture to deliver unmatched analog performance and maximize system flexibility with an on-chip oscillator, output volume control with soft ramp and zero crossing, selectable digital filter response and integrated level shifters for direct interface to logic levels from 2.5 V to 5 V. The on-chip oscillator eliminates the need for an external crystal oscillator circuit, thereby reducing overall design cost and conserving circuit board space. The CS4272 automatically uses the on-chip oscillator in the absence of an applied main clock, simplifying system design. The wide dynamic range, negligible distortion and premium sound quality of the CS4272 make it the ideal for applications such as digital mixing consoles, effects processors, DVD recorders, set-top box systems and automotive audio systems.
