The resistor improves the circuit
’
s phase margin by iso-
lating 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 (V
DD
= 2.7V), the
amplifiers are disabled, and their outputs are driven to
V
SS
. Since the outputs are actively driven to V
SS
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 independently. 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 I
DD
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).
