ELECTRICAL CHARACTERISTICS

All parameters are measured at T

A

All gains are calculated from equation G = 20 LOG (

∆OUT/∆IN) where ∆OUT and ∆IN are appropriate voltage or current increases.

All resistances are calculated according to equation R = (V

P

- V

Q

) / I

is voltage on the pad loaded with I

COND

current.

V

Q

- quiescent (unbias) voltage measured on the pad, (nothing connected to the pin).

V

P

is the actual voltage measured on the pad at given condition (where P is pad number).
