AD7683: 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.
