High performance stereo audio codec
The Cirrus Logic CS4282P is part of a new series of pro audio converters aimed at providing the most transparent audio conversion. This transparency allows manufacturers to customize their end products. The CS4282P is the highest performing, 32-bit resolution Codec on the market. The device support stereo differential analog inputs/outputs and 32-bit digital out/in via the audio serial port (ASP) at sample rates up to 768 kHz.The ADC use a 5th-order, multibit sigma-delta modulator followed by digital filtering and decimation. This provides a dynamic range of over 123 dB and THD+N below -110 dB, all within a 25 mW/ch power budget. The DAC in the CS4282P uses a proprietary analog FIR architecture to reduce out-of-band noise and minimize the external component requirements. This provides a dynamic range of 129 dB and THD+N below -115 dB.
The device can be powered from a single rail and controlled by either hardware pins, I2C or SPI, making the devices both flexible and easy to integrate. This makes the CS4282P ideal for USB audio interfaces, home audio and audio video receivers, as well as musical instruments such as synthesizers, DJ mixers and amplifiers.
