AD7677:16位、1 LSB INL、1 MSPS、差分PulSAR® ADC
AD7677是一款16位、1 MSPS、1 LSB INL、电荷再分配SAR型、全差分模数转换器(ADC),采用5 V单电源供电。它是全新PulSAR™系列的旗舰产品,同时还是速度最快、业界有史以来精度最高的16位SAR ADC。该器件内置一个16位高速采样ADC、一个内部转换时钟、纠错电路,以及串行和并行系统接口。
The AD7677 is a 16-bit, 1 MSPS, 1 LSB INL, charge redistribution SAR, fully differential analog-to-digital converter that operates from a single 5 V power supply. The AD7677 is the flagship part of the new PulSAR™ family - simultaneously being the fastest as well as the industry's most accurate 16-bit SAR ADC ever introduced . The part contains a high-speed 16-bit sampling ADC, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports.
