3 概要

TAS5780Mデバイスは高性能のステレオ、クローズド・ループ、クラスDアンプで、96kHzアーキテクチャのオーディオ・プロセッサが内蔵されています。デジタルからアナログへの変換を行うため、デバイスは高性能のDACと Burr Brown™オーディオ・テクノロジを使用します。必要な電源は、低電圧回路用のDVDD 1つと、高電圧回路用のPVDD 1つだけです。このデバイスは、標準のI2C通信を使用して、ソフトウェア制御ポートにより制御されます。

rDS(on)が90mΩの出力MOSFETにより、熱性能とデバイスのコストについて最良のバランスが達成されます。さらに、熱的に強化された48ピンTSSOPは、今日のコンシューマ向け電子機器にみられる高い周辺温度において、非常に優れた動作を実現します。
