How to use the disable pin of ADA4807-1

Question

Hello 
 I use ADA4807-1. And I would like to enable this Op Amp always. So I use a 10kohm pull up resistor to connect to 3.3V, which is also the power supply of the Op Amp. 
 However, the Op Amp seems sink a lot of current. Then I change the resistor to 1Megohm. It seems the Op Amp works well. 
 I wonder why and How should I pull up this disable pin? 
 
 Thanks in advance!

Hello YunFANG , For more details regarding the Disable pin, you can refer to this section from the data sheet: Looking at figure 64 and table 10, I think a voltage of ~1.5V should be enough to enable the part. I would also recommend using different supply voltage equipment/source for the supply voltage pin and disable pin. Regards, Paul)
