    Product Details:

    AD7902是一款双通道16位、逐次逼近型analog-to-digital converter(ADC)，各ADC采用单电源(VDDx)供电。 它内置两个低功耗、高速、16位采样ADC和一个多功能串行端口接口(SPI)。在CNVx上升沿，AD7902对IN+与参考地IN−之间的模拟输入电压进行采样，范围从0 V至VREF。 REFxAnalog66引脚的基准电压(VREF)由外部提供，可独立于电源电压引脚(VDDx)来设定。该器件的功耗与吞吐速率呈线性变化关系。

    The SPI-compatible serial interface also daisy-chains several ADCs to a single three-wire bus using SDIx inputs and provides an optional busy indication. It is compatible with 1.8V, 2.5V, 3V, and 5V logic when using the standalone power supply VIOx.

    The AD7902 is available in a 20-pin QSOP package and has an operating temperature range of −40°C to +125°C.
