rail–to–rail output swing. In order to obtain this
performance, V
must be externally driven to
V
/2, perhaps by use of the circuit of
Figure 11
.
At V
near 2.5V and V
= 4.75V, the typical
positive output headroom at the DAC is limited
to 1.15V above 2.5V, so that this circuit is useful
for rail–to–rail outputs for gains higher than
4.35 (i.e. 1.15V
PP
maximum input). Note that
while an AC–coupled input is shown, this cir-
cuit is just as useful for DC–coupled inputs
which are generated with respect to the V
pseudoground voltage. R
is used for the
AC–coupled circuit for opamp bias current re-
turn when the DAC is programmed to code 0, as
no current flows into V
(X) at code 0.
