Hello everyone,

I have checked iso122jp using breadboard, it gives no response

As in Diagram, I have given 0 - 2VDC input in pin 15&16 and 15VDC in pin 1&2. Then using multimeter I measured output in pin 7&8 it shows only Zero there is no response upto 12VDC on pin 15&16.
Kindly advice me to use iso122jp in my circuit.

Did you include the bypass capacitors for all the supply pins in your circuit on the breadboard?

 

Is the input power supply connected to the input common and the output supply connected to the output common?

 

yes, I have connected input to input gnd and output to output gnd.

No, i have not connected any capacitor. is it necessary to connect capacitors?
