儀表放大器

ADI公司的儀表放大器是精密增益模塊,輸入為差分式,輸出可以是差分式,也可以是相對于參考端的單端式。這些器件能夠放大兩個輸入信號電壓之間的差值,同時抑制兩個輸入端共有的任何信號。儀表放大器廣泛用于許多工業、測量、數據采集和醫療應用,這些應用要求在高噪聲環境下保持直流精度和增益精度,而且其中存在大共模信號(通常為交流電力線頻率)。

儀表放大器鉆石圖工具

鉆石圖工具是一個網絡應用程序,可生成特定配置的輸出電壓范圍與輸入共模電壓關系圖,也被稱為鉆石圖,適用于ADI儀表放大器。 根據電源電壓、增益和輸入信號范圍等用戶輸入參數,該工具可檢測設計飽和情況,推薦合適的儀表放大器使輸入信號在規格范圍內并且配置的電路是有效的。 該工具能避免設計飽和,找到適合設計的最佳儀表放大器,節省設計時間。
