Power Supplies and Layout

The MAX4230–MAX4234 can operate from a single

2.7V to 5.5V supply, or from dual ±1.35V to ±2.5V sup-

plies. For single-supply operation, bypass the power

supply with a 0.1µF ceramic capacitor. For dual-supply

operation, bypass each supply to ground. Good layout

improves performance by decreasing the amount of

stray capacitance at the op amps’ inputs and outputs.

Decrease stray capacitance by placing external com-

ponents close to the op amps’ pins, minimizing trace

and lead lengths.
