CS5529-AS集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

CS5529-AS属于集成电路（IC）的模数转换器（ADC）。由凌云逻辑制造生产的CS5529-AS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。

General Description

The 16-bit CS5529 is a low-power, programmable ∆Σ ADC (Analog-to-Digital Converter), which includes coarse/fine charge buffers, a fourth-order ∆Σ modulator, a calibration microcontroller, a digital filter with programmable decimation rates, a 6-bit output latch, and a threewire serial interface. The ADC is designed to operate from single or dual analog supplies and a single digital supply.
