All MAX534 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
a 0V to +4V (or +4V to 0V) output transition, the amplifi-
er outputs will typically settle to 1/2LSB in 8µs when
loaded with 10kΩ in parallel with 100pF.
The buffer amplifiers are stable with any combination of
resistive (≥10kΩ) or capacitive loads.
