製品

Overview

NCS2211 は、高性能、低歪みのクラス A/B オーディオ・アンプです。8 Ω スピーカ Bridge-tied Load (BTL) に 1W の出力電力を提供できます。NCS2211 は広い温度範囲で動作し、携帯用アプリケーションにおいて単一供給電圧で動作するように仕様が規定されています。低歪み性能、1.0 W で 0.2% 標準 THD + N を備え、バッテリ寿命を延ばすため、シャットダウン/イネーブル機能を搭載しています。このシャットダウン/イネーブル機能により、静止電流が最大 1 µ A まで引き下げられます。NCS2211 は、-40°C から +85°C の温度範囲で動作するように設計され、8 リード SOIC パッケージと 3x3 mm DFN8 パッケージで提供されます。SOIC パッケージは、DFN8 パッケージと同じく、同等の機能とピン互換であり、競合他社のデバイスに匹敵する性能を持ちます。DFN8 の熱抵抗は低くわずか 70°C/W で、さらに銅 PCB 基板への熱伝導を促進する金属パッドが露出しています。低歪み、高電力、低静止電流、小型パッケージの NCS2211 は、ノート PC やデスクトップ PC、PDA、スピーカフォンなどのアプリケーションに最適です。
