Analog-digital converter CS4302P

audioI2C2-channel

The Cirrus Logic CS4302P 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 CS4302P is a high-performance, 32-bit resolution 2-channel DACs. The device support differential analog outputs and 32-bit digital input via the audio serial port (ASP) at sample rates up to 768 kHz.The CS4302P 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 CS4302P ideal for digital mixers, USB audio interfaces, home audio and audio video receivers, plus musical instruments such as synthesizers, DJ mixers and amplifiers. Features High-performance Stereo DAC Differential analog outputs High-resolution 32-bit digital architecture Low-latency digital filters and digital volume control PLL supports range of external system-clock references Synchronous operation across multiple devices Audio serial port (ASP) sample rates up to 768 kHz I2S, left-justified, and TDM data formats DSD up to 512xfs Hardware and software control modes Hardware control with no host processor required I2C control port up to 1 MHz SPI control port up to 24 MHz Single-supply operation at 3.3 V Support for 1.8 V–3.3 V digital input/output
