CS5540集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

CS5540属于集成电路（IC）的模数转换器（ADC）。由凌云逻辑制造生产的CS5540模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

描述 Description

The CS5540 is a low-power and low-voltage ∆Σ analog-to-digital converter (ADC), which achieves highly accurate conversions using a simple non-programmable interface that is easy to understand and design-in. It is optimized to convert analog signals in DC measurement applications, such as temperature and pressure measurement, and various portable devices where low-power consumption is required.
