3 概要

TAS6424-Q1デバイスは、4チャネルのデジタル入力、Class-Dオーディオ・アンプで、2.1MHzのPWMスイッチング周波数が実装されているため、非常に小さなサイズのPCBでコスト最適化されたソリューションを実現可能です。開始/停止イベントについて最低4.5Vで完全な動作を行い、最高40kHzのオーディオ帯域幅で非常に優れた音質を提供します。

TAS6424-Q1 Class-Dオーディオ・アンプは、車載用ヘッドユニット、および外部アンプ・モジュールで使用するよう設計されています。このデバイスには4つのチャネルがあり、14.4V電源から4Ω負荷へ10% THD+Nで27Wを、2Ω負荷へ10% THD+Nで45Wを、25V電源から4Ω負荷へ10% THD+Nで75Wを供給できます。Class-Dトポロジにより、従来のリニア・アンプ・ソリューションと比較して劇的に効率が向上しています。出力スイッチング周波数をAMバンドよりも高く設定すると、AMバンドの干渉を排除し、出力フィルタのサイズとコストを削減できます。また、AMバンドよりも低く設定すれば、効率を最適化できます。
