where the slew rate (SR) is 3V/µs. Figure 2 shows the

full-power bandwidth as a function of the peak-to-peak

AC output voltage.

Power-Up Conditions

The MAX4493/MAX4494/MAX4495 typically settle within

3µs after power-up. See Power-Up Time in Typical

Operating Characteristics.

Power Supplies and Layout

The MAX4493/MAX4494/MAX4495 operate with dual

supplies from ±2.25V to ±5.5V. Bypass both VCC and

VEE with their own 0.1µF capacitor 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.
