Notes:
1) External bypass capacitors should be placed as close to the package as possible.
2) Dual biasing sequence required:
a. Turn-on Sequence: Apply V
g1
= -2.5V, V
g2
= -2.5V, followed by V
d1
= V
d2
= 7V, lastly increase
V
g1
& V
g2
in sequence until required I

is obtained.
b. Turn-off Sequence: Turn off V
