AD7683ARM: 100 kSPS、16位 PulSAR® ADC,采用µSOIC/QFN封装
AD7683是一款16位、电荷再分配、逐次逼近型PulSAR®模数转换器（ADC）,采用2.7 V到5.5 V的单电源（VDD）供电。它内置一个低功耗、高速、16位不失码的采样ADC（B级）、一个内部转换时钟和一个串行SPI兼容接口。该器件还集成了一个低噪声、宽带宽、短孔径延迟的采样保持电路。在CS下降沿,AD7683对IN+与IN-之间的电压差进行采样,范围从0V至REF。基准电压（REF）由外部提供,最高可以设置为电源电压,其功耗和吞吐量呈线性关系。AD7683采用8引脚MSOP或8引脚QFN （LFCSP）封装,工作温度范围为−40°C～+85°C。
The AD7683 is a 16-bit, charge redistribution, successive approximation, PulSAR® analog-to-digital converter (ADC) that operates from a single power supply, VDD, between 2.7 V and 5.5 V. It contains a low power, high speed, 16-bit sampling ADC with no missing codes (B grade), an internal conversion clock, and a serial, SPI-compatible interface port. The part also contains a low noise, wide bandwidth, short aperture delay, track-and-hold circuit. On the CS falling edge, it samples an analog input, +IN, between 0 V to REF with respect to a ground sense, –IN. The reference voltage, REF, is applied externally and can be set up to the supply voltage. Its power scales linearly with throughput.
The AD7683 is housed in an 8-lead MSOP or an 8-lead QFN (LFCSP) package, with an operating temperature specified from −40°C to +85°C.
