Output Buffer
The MAX1102/MAX1103/MAX1104 analog output is
internally buffered by a precision unity-gain buffer that
slews at 1.2V/µs (typ). The output swings from GND to
V_DD - 0.1V. With a 0 to V_DD - 0.1V (or V_DD - 0.1V to 0)
output transition, the amplifier output typically settles to
1/2LSB in 11µs when loaded with 10kΩ in parallel with
100pF.
The buffer amplifier is stable with any combination of
resistive (≥ 10kΩ) or capacitive (≤ 100pF) loads.
