Note 1: All devices are 100% production tested at T
A
= +25°C. Specifications over temperature are guaranteed by design.
Note 2: Voltage gain (A
V
) is a two-point measurement in which the output voltage swing is divided by the input voltage swing.
Note 3: With an output load attached, this offset will directly contribute to quiescent current.
