The resistor improves the circuit’s phase margin by isolat-
ing the load capacitor from the op amp’s output.
Power-Up and Shutdown Modes
The MAX4231/MAX4233 have a shutdown option. When
the shutdown pin (SHDN) is pulled low, supply current
drops to 0.5μA per amplifier (VDD = 2.7V), the amplifiers
are disabled, and their outputs are driven to VSS. Since
the outputs are actively driven to VSS in shutdown, any
pullup resistor on the output causes a current drain from
the supply. Pulling SHDN high enables the amplifier. In
the dual MAX4233, the two amplifiers shut down indepen-
dently. Figure 10 shows the MAX4231’s output voltage
to a shutdown pulse. The MAX4231–MAX4234 typically
settle within 5μs after power-up. Figures 11 and 12 show
IDD to a shutdown plus and voltage power-up cycle.
When exiting shutdown, there is a 6μs delay before the
amplifier’s output becomes active (Figure 10).
