Hello,

 

I use ADG1612 in my product. Supply power is 12V single supply and input power is 5V with 10k resistors in serial at one cha.


12V supply, 220ohm resistors used to limit current. While the maximum current must be 54mA , 47mA happening. When I measure the voltage drain and source I see that 1.35 volts. 1.35 / 0,047 = Calculated values of 28.72 ohm.


Where am I doing wrong? Please Help.


Note: i am sorry.  My English very bad..
