Microchip微芯 EMC1814 产品介绍
说明
EMC1814是一款1.8V、4通道、高精度、2线(I2.C兼容)温度传感器。变化率、电阻误差校正(REC)、贝塔补偿(支持需要BJT/晶体管型号的CPU二极管)和理想配置等高级功能相结合,为复杂的环境监测应用提供了强大的解决方案。
EMC1814显示器是第一个引入变化率功能的设备系列。除了温度本身,这些数据还有助于抢先系统f。这种类型的数据可以帮助客户更好地调节他们的应用程序控制温度。
电阻误差校正自动消除由串联电阻引起的温度误差,从而使热敏二极管的布线更加灵活。贝塔补偿消除了由当今精细几何处理器中常见的低可变贝塔晶体管引起的温度误差。这使得用户无需为每个温度监测应用程序提供独特的传感器配置。这些先进的功能加上±1°的测量精度,为关键温度监测应用提供了一种低成本、高度灵活和准确的解决方案。
