AD7684: 16位、100 kSPS PulSAR®、差分ADC,采用MSOP封装
AD7684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至5.5 V单电源（VDD）供电。该器件内置一个低功耗、高速、16位无失码采样ADC、一个内部转换时钟和一个串行、SPI兼容接口,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,该器件对+IN与-IN引脚之间的电压差进行采样。基准电压（REF）由外部提供,最高可设置为电源电压,其功耗和吞吐量呈线性变化关系。AD7684采用8引脚MSOP封装,工作温度范围为−40°C至+85°C。
The AD7684 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 to 5.5 V. It contains a low power, high speed, 16-bit sampling ADC with no missing codes, 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 the voltage difference between +IN and –IN pins. The reference voltage, REF, is applied externally and can be set up to the supply voltage. Its power scales linearly with throughput.The AD7684 is housed in an 8-lead MSOP, with an operating temperature specified from −40°C to +85°C.
