1.3 Test Circuit
The circuit used for most DC and AC tests is shown in
Figure 1-1. This circuit can independently set V
CM
and
V
OUT
; see Equation 1-1. Note that V
CM
is not the
circuit’s common mode voltage ((V
P
+V
M
)/2), and that
V
OST
includes V
OS
plus the effects (on the input offset
error, V
OST
) of temperature, CMRR, PSRR and A
OL
.
