CS5308P中文资料32位透明模数转换器数据手册CirrusLogic规格书

描述 Description

The CS5308P is part of a new series of pro audio converters aimed at providing the most transparent audio conversion within one device that is simple to use and integrate. The CS5308P is a high-performance, 32-bit resolution, eight-channel ADC that supports differential analog input and 32-bit digital output via the audio serial port (ASP) at sample rates up to 768 kHz. CS5308P 采用了 5 阶多位 sigma-delta 调制器，以及数字滤波和抽取技术。因此，其动态范围超过 123 dB，总谐波失真加噪声 (THD+N) 低于 -110 dB，全部在 25 mW/ch 功率预算范围内。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 new hybrid gain control feature, makes the CS5308P ideal for digital mixing consoles, DAW interfaces, effects processors and audio/video receivers.
