The PCM4201 is designed for digital audio applications that require a combination of high dynamic range, low distortion, and low power consumption. The primary applications for the PCM4201 include digital wireless microphones and battery-operated audio recording or processing equipment. The PCM4201 outputs 24-bit linear PCM audio data at sampling rates up to 108kHz. Three sampling modes allow the user to trade off power for performance, dependent upon the intended system requirements. An on-chip voltage reference reduces the number of external components needed for operation.
The PCM4201 includes dedicated control pins for configuration of all programmable functions. The device requires a +5.0V analog power supply, in addition to a digital supply operating from +1.8V to +3.3V. The PCM4201 is available in a small TSSOP-16 package.

PCM4201EVM — PCM4201 評估模組 (EVM)
PCM4201EVM 是一個方便好用的平台，適用於評估單通道 PCM4201 音訊裝置的性能和功能。EVM 具有差動類比輸入通道。此通道會使用低雜訊輸入電路（德州儀器 OPA2134 雙運算放大器）來緩衝和篩選。此訊號會傳送到 PCM4201 的輸入處，並在該處轉換為 PCM 訊號。此 PCM 輸出可在接頭 J3 處取得。音訊資料會路由至德州儀器 DIT4096，並透過 BNC J5 輸出。AES3 編碼輸出可連接至音訊測試系統或商用音訊設備。
