Rail-to-Rail I/O Op Amps with Shutdown

Do not three-state SHDN. Due to the output leakage
currents of three-state devices and the small internal
pull-up current for SHDN, three-stating this pin could
result in indeterminate logic levels, and could adversely
affect op-amp operation.
The logic threshold for SHDN is always referred to VEE,
not GND. When using dual supplies, pull SHDN to VEE
to place the op amp in shutdown mode.
Power Supplies and Layout
The MAX4330–MAX4334 operate from a single +2.3V
to +6.5V power supply, or from dual ±1.15V to ±3.25V
supplies. For single-supply operation, bypass the
power supply with a 0.1F capacitor to ground (VEE).
For dual supplies, bypass both VCC and VEE with their
own set of capacitors to ground.
Good layout technique helps optimize performance by
decreasing the amount of stray capacitance at the op
amp’s inputs and outputs. To decrease stray capaci-
tance, minimize trace lengths by placing external com-
ponents close to the op amp’s pins.
