Output Buffer Amplifiers
All MAX533 voltage outputs are internally buffered by
precision unity-gain followers that slew at about
0.6V/μs. The outputs can swing from GND to V
DD
. With
a 0V to +2.5V (or +2.5V to 0V) output transition, the
amplifier outputs will typically settle to 1/2LSB in 6μs
when loaded with 10k
in parallel with 100pF.
The buffer amplifiers are stable with any combination of
resistive (
10k
) or capacitive loads.
__________Applic ations Information
DAC Linearity and V oltage Offset
The output buffer can have a negative input offset volt-
age that would normally drive the output negative, but
since there is no negative supply the output stays at 0V
(Figure 9). When linearity is determined using the end-
point method, it is measured between zero code (all
inputs 0) and full-scale code (all inputs 1) after offset
and gain error are calibrated out. However, in single-
supply operation the next code after zero may not
change the output (Figure 9), so the lowest code that
produces a positive output is the lower endpoint.
