ADG1221 No output voltage

Hi RamiSahbi, 

Your code is fine. It is kind a weird though that INx stays high all the time and the one you're controlling pin 13 and 10 which is the supply input. The state of the switch depends on INx, so normally we connect our control signal to Inx.

If you have dmm around, you can do a continuity test between S1-D1 and S2-D2 while putting 5V and 0V to IN1/IN2. This is to check if the switch is still functioning. Make sure that the device has supply and Vss is connected to Gnd.

You should expect the following response.

Hi RamiSahbi,

Are you trying to turn on and turn off the two LED DI and D2?

yes, I want to know how to activate and enable the switchb because I followed this steps: 

1. Turn IN1 and IN2 into HIGH to activate all switches
2. Then I send a HIGH signal to D1 and D2.
3. Normally here I expect all leds are on
4. after that I send a LOW signal to D and D2 to turn off all leds

Hi RamiSahbi,

please detail the following in your design

1. power supply voltage level to the switch

2. analogue voltage on D1 and D2

If the switch closes expect an additional => 120 Ohm of resistance added to R1 and R2 in your design.
