_______________General Description

The single MAX473, dual MAX474, and quad MAX475

are single-supply (2.7V to 5.25V), unity-gain-stable op

amps with rail-to-rail output swing. Each op amp guar-

antees a 10MHz unity-gain bandwidth, 15V/µs slew

rate, and 600

Ω drive capability while typically consum-

ing only 2mA supply current. In addition, the input

range includes the negative supply rail and the output

swings to within 50mV of each supply rail.

Single-supply operation makes these devices ideal for

low-power and low-voltage portable applications. With

their fast slew rate and settling time, they can replace

higher-current op amps in large-signal applications.

The MAX473/MAX474/MAX475 are available in DIP and

SO packages in the industry-standard op-amp pin

configurations. The MAX473 and MAX474 are also

offered in the µMAX package, the smallest 8-pin SO.
