the first question:In the reference SCH DC2425A，LT1819 is supplied by +6/-6v. Is it ok if the chip is supplied by +5/-5V? In the datasheet, it says Specifi ed at ±5V, Single 5V Supplies, why it supplied by +6/-6V?
the second question, the following is my design which I modify according to DC2425A.Can you help me to check is it right?
In my design, I use two single ADC, is it ok if I use one Precision reference voltage source to supply the pin REFOUT of two ADCS?
