Abstract

The AD1781 produced by Analog Devices,Inc.is 24-Bit Σ-Δ A/D converter for the high-speed industry data acquasition system.Because it is serial output,when it is connected with MCU,the sampling rate can not keep up with.The interface circuit between AD1871 and MCU is designed using VHDL and FPGA to resolve this problem.The program and emulation are given.
