I want to use the ADG419BR analog switch device with single  15V supply and  5V
logic supply.
The data sheet recommends using  12V single supply or dual supply of  15V and –
15V.
1. Can I use  15V single supply instead of  12V supply?
2. What could be the influence of rising the single supply voltage?

 

1. Can I use  15V single supply instead of  12V supply?
Yes, you can use a single supply of up to approx 20V, but the part is only
tested for ±15V and 0-12V operation.
2. What could be the influence of rising the single supply voltage?
Main difference would be an increase in the allowable input signal swing and a
slight reduction in on-resistance, refer to figure 4 in the datasheet for a
typical curve.
