Sv: [sdiy] cheapest 30V analog switch

[Harry Bissell Jr]

I use the DG444

I don't know about Europe, bu the 1K pricing on the
Maxim site is around $1 so its probably less
expensive than the DG201

It need a logic voltage reference suppy, though..
could be as simple as a resistive divider or cheap
zener (what I use)

The DG441/442 is the same spec whithout the logic
supply needed. I have not tried them
