TDC7200 是一款時(shí)間 - 數(shù)字轉(zhuǎn)換器 (TDC)，適用于水表、燃?xì)獗砗蜔崃坑?jì)等超聲波感測(cè)裝置。 與 TDC1000（超聲波模擬前端）配套使用時(shí)，TDC7200 可與 MSP430、電源、無(wú)線器件以及相關(guān)源代碼一起構(gòu)成一套完整的德州儀器 (TI) 超聲波感測(cè)解決方案。
時(shí)間數(shù)字轉(zhuǎn)換器 (TDC) 可執(zhí)行秒表功能，測(cè)量 START 脈沖與多達(dá) 5 個(gè) STOP 脈沖之間的時(shí)間間隔（渡越時(shí)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(nèi)置自校準(zhǔn)時(shí)基，可對(duì)時(shí)間和溫度偏差進(jìn)行補(bǔ)償。 這一自校準(zhǔn)功能使得時(shí)間數(shù)字轉(zhuǎn)換器能夠獲得皮秒級(jí)精度。 因此，TDC7200 非常適用于注重高精度零流量和低流量測(cè)量的流量計(jì)應(yīng)用。
TDC7200 置于自主多周期平均模式下時(shí)，可降低系統(tǒng)功耗，非常適合電池供電式流量計(jì)。 在此模式下，主器件會(huì)進(jìn)入休眠模式以實(shí)現(xiàn)節(jié)能，并會(huì)在測(cè)量序列完成后由 TDC 中斷喚醒。
