Dear forum Members,
I experienced the supply current is too high if device output saturated (however, not loaded!). One of the channels used as comparator and the other one in linear mode.
If comparator output settleted to VSS then supply current is ca 5,5uA, at VDD the current ca 13uA ("+" input is tied to 1,2V, "-" is to VSS)
If both channels are operated in linear mode the current drawn is onyl 1,7uA as specified (for this condition "comparator" channel formed to an unity gain buffer with "+" =1,2V).
Supply voltage is 7V (single supply application).
Is this property normal for this device? If so, can you please expalin why the current draw varies despite the output is left unconnected?
Can you please suggest a solution becasue the need for low current is critical my design.
Thanks in advance!
Regards,
Joseph
