Overview
The ISO7762DBQEVM from Texas Instruments is an evaluation module for the ISO7762, a high-performance, six-channel digital isolator. This device is designed to provide robust isolation and high electromagnetic immunity, making it suitable for a variety of applications requiring reliable and isolated digital signal transmission.
The ISO7762 family, including the DBQ package, offers up to 3000 VRMS isolation rating per UL 1577 and is certified according to several safety standards, including VDE, CSA, TUV, and CQC. Each isolation channel features a logic-input and logic-output buffer separated by a double capacitive silicon dioxide (SiO2) insulation barrier.
