AD7944是一款14位、2.5 MSPS逐次逼近型模数转换器(SAR ADC)。它内置一个低功耗、高速、14位采样ADC、一个内部转换时钟、一个内部基准电压源（和缓冲）、纠错电路以及一个多功能串行接口端口。在CNV上升沿，AD7944对IN+与IN-之间的模拟输入电压差进行采样，范围从0 V至VREF。该器件具有两种采样模式：极高采样速率turbo模式（TURBO高）；低功耗正常模式（TURBO低），适用于低功耗应用，其功耗与吞吐量呈比例关系。正常模式（TURBO低）下，SPI兼容型串行接口还能够利用SDI输入，将几个ADC以菊花链形式串联到单三线式总线上，并提供一个可选的忙闲指示。采用独立电源(VIO)时，该串行接口与1.8 V、2.5 V和2.7 V电源兼容。\n\n AD7944采用20引脚LFCSP封装，工作温度范围为−40°C至+85°C。\n\n
