ADUM5000 gives high output

Hi All,

 

I have designed a circuit with ADUM5000 as isolator. The input to the IC is 3.3V and the configuration is: RCin pull down, RCsel is pulled up and VSEL is pull down.  All resistors are 4.7K. there are 10uf and 0.1uf caps on all recommended pins for input and output power.

 

The load is around 10mA. The output voltage is only 2.6V.

 

If i disconnect the load then the voltage is 6V.

 

What could be the possible problem.
