ディスプレイおよび照明IC

アナログ・デバイセズは、自動車用からディスプレイおよびキーパッドLEDのバックライト・アプリケーションまで、幅広い用途を対象にしたLEDドライバ群を提供しています。
AD8240などの製品はLEDアセンブリの駆動とモニターを行う一方で、LED駆動を単純化することによってシステム・コストを低減します。
ADP8860/ADP8870チャージ・ポンプLEDドライバは、最大7個の白色LEDを並列で駆動できるように設計されており、周囲光の条件に基づいて自動的に輝度調整を行うためのコントローラが組み込まれています。これらのインテリジェント・ステート・マシン製品は、プロセッサの介在を減らすことによってバッテリ寿命を延長するとともに、ソフトウェアの複雑さを緩和することによって市場投入までの時間を短縮します。
