AD7671: 16位、1 MSPS双极性PulSAR® ADC
AD7671基于将速度推至极限的突破性PulSAR™内核,是一款16位、1 MSPS电荷再分配SAR型模数转换器(ADC),采用5 V单电源供电。它内置一个高速16位采样ADC、一个接受各种输入范围的电阻器输入标量、一个内部转换时钟、纠错电路,以及串行和并行系统接口。AD7671是业界最快的16位SAR ADC,而且是业界首款打破1 MSPS限制的ADC。
Pushing the speed limit of the breakthrough PulSAR™ core, the AD7671 is a 16-bit, 1 MSPS, charge redistribution SAR Analog-to-Digital Converter that operates from a single 5 V power supply. It contains a high-speed 16-Bit sampling ADC, a resistor input scalar, which allows various input ranges, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.The AD7671 is the fastest 16-bit SAR ADC in the industry and the world's first to touch the 1 MSPS barrier.
