Definition of Terms
Input offset voltage:That voltage which must be applied between the input terminals to bias the unloaded
output in the linear region.
Input offset current:The difference in the currents at the input terminals when the unloaded output is in the
linear region.
Input bias current:The absolute value of the average of the two input currents.
Input resistance:The ratio of the change in input voltage to the change in input current on either input with the
other grounded.
Large signal voltage gain:The ratio of the specified output voltage swing to the change in differential input
voltage required to produce it.
Shunt gain:The ratio of the specified output voltage swing to the change in differential input voltage required to
produce it with the output tied to the V
+
terminal of the IC. The load and power source are connected
between the V
+
and V
−
terminals, and input common-mode is referred to the V
−
terminal.
Common-mode rejection:The ratio of the input voltage range to the change in offset voltage between the
extremes.
Supply-voltage rejection:The ratio of the specified supply-voltage change to the change in offset voltage
between the extremes.
Line regulation:The average change in reference output voltage over the specified supply voltage range.
Load regulation:The change in reference output voltage from no load to that load specified.
Feedback sense voltage: The voltage, referred to V
−
, on the reference feedback terminal while operating in
regulation.
Reference amplifier gain:The ratio of the specified reference output change to the change in feedback sense
voltage required to produce it.
Feedback current: The absolute value of the current at the feedback terminal when operating in regulation.
Supply current:The current required from the power source to operate the amplifier and reference with their
outputs unloaded and operating in the linear range.
