5 说明 (续)

高分辨率通道可支持更大的感测范围,在两倍线圈直径范围外依然可保持良好的性能。良好匹配的通道支持差分与比率测量,因此,设计人员能够利用一个通道来补偿感测过程中的环境条件和老化条件,例如温度、湿度和机械漂移等。

得益于易用、低能耗、低系统成本等特性,这些米6体育平台手机版_好二三四有助于设计人员大幅提高现有传感解决方案的性能、可靠性和灵活性,从而为所有市场(尤其是消费品和工业应用)中的米6体育平台手机版_好二三四引入全新的感测 功能。。

这些器件可以通过 I2C 接口轻松进行配置。双通道 LDC1612-Q1 采用 WSON-12 封装,四通道 LDC1614-Q1 采用 WQFN-16 封装。
