3 說明
TDC7200 是一款時間 - 數字轉換器 (TDC)，適用于水表、燃氣表和熱量計等超聲波感測裝置。 與 TDC1000（超聲波模擬前端）配套使用時，TDC7200 可與 MSP430、電源、無線器件以及相關源代碼一起構成一套完整的德州儀器 (TI) 超聲波感測解決方案。
時間數字轉換器 (TDC) 可執行秒表功能，測量 START 脈沖與多達 5 個 STOP 脈沖之間的時間間隔（渡越時間，即 TOF）。 這一功能使得用戶能夠靈活選擇回聲性能最佳的 STOP 脈沖。
該器件內置自校準時基，可對時間和溫度偏差進行補償。 這一自校準功能使得時間數字轉換器能夠獲得皮秒級精度。 因此，TDC7200 非常適用于注重高精度零流量和低流量測量的流量計應用。
TDC7200 置于自主多周期平均模式下時，可降低系統功耗，非常適合電池供電式流量計。 在此模式下，主器件會進入休眠模式以實現節能，并會在測量序列完成后由 TDC 中斷喚醒。
