Typical data is at T
A
= 25癈, except for 擲ens, and at x.x Sens. Typical data are for initial design estimations only, and assume optimum
manufacturing and application conditions. Performance may vary for individual units, within the speci ed maximum and minimum limits.
In addition, the typical values vary with gain.
