The ADS8320 device is a 16-bit, sampling analog-to-digital (A/D) converter with ensured specifications over a 2.7-V to 5.25-V supply range. It requires very little power even when operating at the full 100-kHz data rate. At lower data rates, the high speed of the device enables it to spend most of its time in the power-down mode. The average power dissipation is less than 100 mW at 10-kHz data rate.

The ADS8320 also features operation from 2 V to 5.25 V, a synchronous serial (SPI/SSI compatible) interface, and a differential input. The reference voltage can be set to any level within the range of 500 mV to VCC.

Ultra-low power and small size make the ADS8320 ideal for portable and battery-operated systems. It is also a perfect fit for remote data acquisition modules, simultaneous multi-channel systems, and isolated data acquisition. The ADS8320 is available in an 8-pin VSSOP package.

TIDM-WLMOTORMONITOR — 無線馬達監控器參考設計

此參考設計受監控馬達和機器健康狀況的需求所啟發，可準確預測和安排維護（或更換），同時將工業生產期間的成本和停機時間降到最低。目前透過手持或有線壓電加速度計感測裝置，監控數百萬個工業馬達。超低功耗處理技術、無線電及壓電感測器微型化的最新進展，促成了開發和部署具無線功能的低成本小型馬達監控器。這些無線馬達監控器皆由電池壽命超過 10 年的鈕釦電池供電。這些系統提供與現有手持系統相同的寬頻靈敏度、收集振動資料並對這些資料進行頻譜分析。這種整合智慧可讓您在不易觸及的位置部署和監控這些系統。無線馬達監控參考設計採用兩種不同、但在電氣方面等效的體積來進行開發與測試。

這些外型尺寸包括：

  • 模組化外型
  • 尺寸精巧
