EVAL-AD7984CBZ开发板套件编程器的评估板-模数转换器（ADC）规格书PDF中文资料

EVAL-AD7984CBZ属于开发板套件编程器的评估板-模数转换器（ADC）。由亚德诺半导体技术有限公司制造生产的EVAL-AD7984CBZ评估板 - 模数转换器（ADC）模数转换器 (ADC) 评估板是预装有元器件的电路板，用于提供特定 ADC 或器件工作实例。特定板上的 A/D 转换器数量从 3 到 32 不等，每秒采样率从 2.5 kHz 到 26 GHz 不等，输入电压范围从 0 到 8 Vp-p。

GENERAL DESCRIPTION

The AD79841 is an 18-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 18-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, the AD7984 samples the voltage difference between the IN+ and IN− pins. The voltages on these pins usually swing in opposite phases between 0 V and VREF. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD.
