ADA4899 disable pin

Hi,

 

according to data sheet the ADA4899 works in normal mode if disable pin is left open.

Below 2,4V it is disabled, above 4,3V it is enabled with 'Low Input Bias Current' .

 

Is a voltage 2,4V ... 4,3V also allowed to enable normal mode?

 

The ADA4899 disable pin should be directly connected to a TTL output, where 3,3V should be equal to enabled

 

Thanks,

Jochen
