Power Supplies and Layout

The MAX4130–MAX4134 operate from a single +2.7V

to +6.5V power supply, or from dual supplies of ±1.35V

to ±3.25V. For single-supply operation, bypass the

power supply with a 0.1µF ceramic capacitor in parallel

with at least 1µF. For dual supplies, bypass each sup-

ply to ground.

Good layout improves performance by decreasing the

amount of stray capacitance at the op amp’s inputs

and outputs. Decrease stray capacitance by placing

external components close to the op amp’s pins, mini-

mizing trace lengths and resistor leads.
