The ISO776x devices are high-performance, six-channel digital isolators with 5000-VRMS (DW package) and 3000-VRMS (DBQ package) isolation ratings per UL 1577. This family of devices is also certified according to VDE, CSA, TUV and CQC.

The ISO776x family of devices provides high-electromagnetic immunity and low emissions at low-power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic-input and logic-output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier. The ISO776x family of devices is available in all possible pin configurations such that all six channels are in the same direction, or one, two, or three channels are in reverse direction while the remaining channels are in forward direction. If the input power or signal is lost, the default output is high for devices without suffix F and low for devices with suffix F. See the Device Functional Modes section for further details.

Used in conjunction with isolated power supplies, this family of devices helps prevent noise currents on data buses, such as RS-485, RS-232, and CAN , 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 the ISO776x family of devices has been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The ISO776x family of devices is available in 16-pin SOIC and SSOP packages.

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。
