GENERAL DESCRIPTION

The AD7475/AD7495 are 12-bit high-speed, low-power, successive-approximation ADCs. The parts operate from a single 2.7 V to 5.25 V power supply and feature throughput rates up to 1 MSPS. The parts contain a low-noise, wide bandwidth track/hold amplifier that can handle input frequencies in excess of 1 MHz.

AD7495BR属于集成电路（IC） > 模数转换器（ADC）。亚德诺半导体技术有限公司制造生产的AD7495BR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。
