High-Output-Drive, 10MHz, 10V/µs,
Rail-to-Rail I/O Op Amps with Shutdown in SC70
The resistor improves the circuit’s phase margin by iso-
lating the load capacitor from the op amp’s output.
The MAX4231/MAX4233 have a shutdown option. When
the shutdown pin (SHDN) is pulled low, supply current
drops to 0.5µA per amplifier (V
fiers are disabled, and their outputs are driven to V
Since the outputs are actively driven to V
down, any pullup resistor on the output causes a cur-
rent 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
plus and voltage power-up cycle.

When exiting shutdown, there is a 6µs delay before the
amplifier’s output becomes active (Figure 10).
