| Abstract: | MAXl320 is a synchronous A/D conversion chip with 14 bit 8 roads produced by Maxim. This paper introduces the characteristics and work principles of MAX1320, discusses the 14 bit 8 roads synchronous data-acquisition circuits made up of MAX1320, and analyzes the interface between MAX1320 and ARM7. This interface realizes the instant sampling with 8 differential inputs, and satisfies the data-acquisition demands of the electric power quality monitoring instrument based on ARM7. |
