• Manufacturer Part Number: MAX533ACEE
• Description: 2.7V, Low-Power, 8-Bit Quad DAC with Rail-to-Rail Output Buffers
• Manufacturer: MAXIM [Maxim Integrated Products]

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
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 10kΩ in parallel with 100pF.
The buffer amplifiers are stable with any combination of
resistive (≥10kΩ) or capacitive loads.

individual CS.

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.
