LTC1966 won't work

Hi Everybody , 

I soldered my LTC1966 on an MSOP to DIP adaptater to test it and see how it works .

So once i had it done i made the following connection, you can see the schematics in the image joint (all the grounds are connected) , my LTC1966 outputs a voltage of 600 mV once it is powered whatever the IN1 Value is .

I don't understand why this is happening.

Can you guys help me please if you know why it is happening or what can i do to debug this problem .
