Part Number: ISO7220A-Q1
In my design , I would like to use ISO7220 to isolate the negetive and positive signal, the signal is send to MCU which is in the positive voltage domain. Is the function right ?
Hi Liang,This application is correct as long as the signal and GND pairs are preserved on each side of the ISO7220A-Q1 as shown in the image below.The microcontroller's 3.3V supply can also be used to power the output side of the isolator. The input side must be powered by a 3V - 5.5V supply referenced to the input side ground, gnd2. Is a supply for this pin available?Thank you for posting to E2E!Manuel Chavez
