詮鼎集團力推ATLab DPI7系列,電容式觸控按鍵解決方案

 2010-08-04
ATLab 自2005年開發出最新的電容式觸控解決方案:DPI7系列並推廣到市場。DPI7系列為純數位製程設計,概念為Differential Input架構方式,完全朝硬體設計概念思考,顛覆以往在傳統Single-end Input設計上必須在線路上加上Shield以及GND來做Sensor pad本身的保護複雜性。其優勢可縮短設計時間以及降低設計上困難度。產品本身也內建自動校正功能(AIC function)對於外殼厚度、材質甚至是曲面的相容性大為增加。且產品本身可接受較大的溫濕度變化、高抗雜訊干擾、ESD甚至在低功率消耗在待機模式下可以達到 70%節能。ATLab DPI7系列解決方案最大的宗旨在於設計容易、不增加產品成本為前提下直接將傳統機械式按鍵替換成電容式觸控按鍵。
