QThe 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.
AConfirm pinout of power pins on soic.
On the AD637 SOIC package, +Vs is pin 13 and -Vs is pin 12.
