AD7920BRMZ-REEL集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD7920BRMZ-REEL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AD7920BRMZ-REEL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 AD7910/AD79201 are, respectively, 10-bit and 12-bit, high speed, low power, successive approximation ADCs. The parts operate from a single 2.35 V to 5.25 V power supply and feature throughput rates up to 250 kSPS. The parts contain a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 13 MHz.
