Q
The AD637 surface mount package (R) has 2 more pins than the DIP(D) and (Q) Packages. Unfortunately the data sheet does not indicate
where the Power Supply pins are on the surface mount package.
On the DIP packages -Vs is on pin 10 and Vs is pin 11. I have
assumed that on the surface mount package -Vs is on pin 12 and
Vs is on pin 13. Please confirm this.
