CS5581-ISZ集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

CS5581-ISZ属于集成电路（IC）的模数转换器（ADC）。由凌云逻辑制造生产的CS5581-ISZ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 CS5581 is a single-channel, 16-bit analog-to-digital converter capable of 200 kSps conversion rate. The input accepts a single-ended analog input signal. On-chip buffers provide high input impedance for both the AIN input and the VREF+ input. This significantly reduces the drive requirements of signal sources and reduces errors due to source impedances. The CS5581 is a delta-sigma converter capable of switching multiple input channels at a high rate with no loss in throughput. The ADC uses a low-latency digital filter architecture.
