AD7091集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD7091属于集成电路（IC）的模数转换器（ADC）。由亚德诺半导体技术有限公司制造生产的AD7091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 AD7091 is a 12-bit successive approximation register analog-to-digital converter (SAR ADC) that offers ultralow power consumption (typically 367 µA at 3 V and 1 MSPS) while achieving fast throughput rates (1 MSPS with a 50 MHz SCLK). The AD7091 operates from a single 2.09 V to 5.25 V power supply. The AD7091 also features an on-chip conversion clock and a high speed serial interface.
