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 V
not GND. When using dual supplies, pull SHDN to V
to place the op amp in shutdown mode.
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 0.1µF capacitor to ground (V
For dual supplies, bypass both V
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.
