The ISO7820 is a high-performance, dual-channel digital isolator with 8000 VPK isolation voltage. This device has reinforced isolation certifications according to VDE, CSA, CQC, and TUV. The isolator provides high electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/O’s. Each isolation channel has a logic input and output buffer separated by silicon dioxide (SiO2) insulation barrier. ISO7820 has two forward channels and no reverse-direction channel. If the input power or signal is lost, default output is ‘high’ for the ISO7820 and ‘low’ for the ISO7820F device. Used in conjunction with isolated power supplies, this device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility of ISO7820 has been significantly enhanced to ease system-level ESD, EFT, Surge and Emissions compliance. ISO7820 is available in 16-pin SOIC wide-body (DW) and extra-wide body (DWW) packages. The DWW package option comes with enable pins which can be used to put the respective outputs in high impedance for multi-master driving applications and to reduce power consumption.

TIDA-01576 — 具有 16 位元 1-MSPS 雙同步取樣 ADC 的高準確度類比輸入模組參考設計

此參考設計在廣泛輸入範圍內,使用精密 16 位元 SAR ADC 準確測量 16 通道 AC 電壓及電流輸入。此範圍涵蓋保護與測量要求 (包括 IEC 61850-9-2 的取樣要求),可簡化系統設計並提升跳脫時間重複性、性能與可靠性。AC 類比輸入模組 (AIM) 使用具有整合電源轉換器或採用六通道的數位隔離器,與主機處理器隔離。在最簡單的配置中,完整的 AC AIM 只需使用五種 TI 產品即可設計,進而實現系統成本與尺寸最佳化。警報功能會以取樣方式識別 AC AIM 故障,以加快故障偵測速度。ADC 具有額外的輔助通道,可診斷數位隔離器電源的輸出,或補償量測類比輸入的溫度漂移。
