Power Supplies and Layout

The LMX321/LMX358/LMX324 operate from a single

+2.3V to +7V power supply. Bypass the power supply

possible.

Good layout techniques optimize performance by mini-

mizing the amount of stray capacitance at the op amp’s

inputs and outputs. Place external components close to

the op amp to minimize trace lengths and stray capaci-

tance.
