_______________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/s slew
rate, and 600
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 MAX package, the smallest 8-pin SO.
