Not Recommended for New Designs
This product was manufactured for Maxim by an outside wafer foundry
using a process that is no longer available. It is not recommended for
new designs. The data sheet remains available for existing users.
A Maxim replacement or an industry second-source may be available.
Please see the QuickView data sheet for this part or contact technical
support for assistance.

Single/Dual/Quad, 10MHz
Single-Supply Op Amps
_______________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 600Ω 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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
