AD7274BRM集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

AD7274BRM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AD7274BRM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 AD7273/AD7274 are 10-bit and 12-bit, high speed, low power, successive-approximation ADCs respectively. The parts operate from a single 2.35V to 3.6 V power supply and feature throughput rates up to 3 MSPS. The parts contain a low-noise, wide bandwidth track/hold amplifier which can handle input frequencies in excess of TBD MHz.

The AD7273/AD7274 use advanced design techniques to achieve very low power dissipation at high throughput rates.

The reference for the parts is applied externally and can be in the range of 1.2V to VDD. This allows the widest dynamic input range to the ADC.
