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.

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

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.
