3 概要

PCMD3180-Q1 は、パルス密度変調 (PDM) 入力を時分割多重 (TDM) 出力または I2S 出力に変換する高性能コンバータであり、PDM マイク入力から取得した最大 8 つのデジタル チャネルの同時サンプリングをサポートしています。このデバイスには、プログラム可能なデジタル ボリューム制御、マイクロフォン バイアス電圧、フェーズ ロック ループ (PLL)、プログラム可能なハイパス フィルタ (HPF)、バイカッド フィルタ、低遅延フィルタ モードが搭載されており、最高 768kHz の出力サンプル レートに対応できます。このデバイスは時分割多重化 (TDM)、I2S、左揃え (LJ) オーディオ・フォーマットに対応し、I2C または SPI インターフェイスで制御可能です。また PCMD3180-Q1 は、オーディオ バス インターフェイス動作をコントローラ モードまたはターゲット モードに選択できます。これらの高性能な機能を搭載しており、3.3V または 1.8V の単一電源で動作できることから、遠距離マイクロフォン録音アプリケーションの、スペースの制約が厳しいオーディオ・システムに最適です。

PCMD3180-Q1 は -40℃～125°Cで動作が規定されており、24 ピンの WQFN パッケージで供給されます。
