Cirrus Logic上月举办数字电能表芯片研讨会,推出其三款ADC新品:CS5460A/CS5451/CS5471。该公司的CS5460系列芯片是在一个单芯片上集成有数字乘法器、数字滤波器及DSP等功能的片上系统,在美国、日本、欧洲已有大量应用,在我国也已经做了长期的推广应用。 CS5460A是针对我国电力特点而设计的,可以用于复费率单相电能表解决方案。CS5460A不仅能直接驱动LCD数字显示,而且可以直接驱动机械字轮计度器显示,可使电能表的精度达到千分之五,使用寿命在十
Cirrus Logic held a digital watthourometer chip seminar last month with its introduction of three new ADCs: the CS5460A / CS5451 / CS5471. The company’s CS5460 family of chips is a system-on-chip with integrated digital multipliers, digital filters, and DSP features on a single chip, and has been used extensively in the United States, Japan and Europe, and has been used in China for a long time . CS5460A is designed for the characteristics of China’s power can be used for multi-rate single-phase energy meter solutions. CS5460A can not only directly drive the LCD digital display, but also can directly drive the mechanical character round meter display, the accuracy of the meter reaches five thousandths, the service life of ten
