CS5312S

High performance 2-channel analog-to-digital converter

CS5312S Overview

The CS5312S is part of a new series of pro audio converters aimed at giving cost-effective transparent audio conversion. All within one device that is easy to use and provides system level cost savings. The CS5312S is a high performance, 32-bit resolution, two-channel ADC. The CS5312S supports differential analog input and 32-bit digital output via the audio serial port (ASP) at sample rates up to 384 kHz. The CS5312S uses a 5th-order, multibit sigma-delta modulator followed by digital filtering and decimation. This provides a dynamic range of over 115 dB and THD+N below -105 dB all within a 25 mW/ch power budget. The device can be powered from a single rail and controlled by either hardware pins, I2C or SPI, making it both flexible and easy to integrate. This, together with Cirrus’s analog gain feature, makes the CS5312S ideal for digital mixing consoles, DAW interfaces, effects processors, musical instruments and audio/video receivers.
