Not Recommended for New Designs The MAX495 was manufactured for Maxim by an outside wafer
foundry using a process that is no longer available. It is not
recommended for new designs. A Maxim replacement or an industry
second-source may be available. The data sheet remains available for
existing users. The other parts on the following data sheet are not
affected. For further information, please see the QuickView data sheet for this
part or contact technical support for assistance.
_______________General DescriptionThe dual MAX492, quad MAX494, and single MAX495
operational amplifiers combine excellent DC accuracy
with rail-to-rail operation at the input and output. Since
the common-mode voltage extends from VCCto VEE,
the devices can operate from either a single supply
(+2.7V to +6V) or split supplies (±1.35V to ±3V). Each
op amp requires less than 150μA supply current. Even
with this low current, the op amps are capable of driving
a 1kΩload, and the input referred voltage noise is only
25nV/√Hz. In addition, these op amps can drive loads in
excess of 1nF.
The precision performance of the MAX492/MAX494/
MAX495, combined with their wide input and output
dynamic range, low-voltage single-supply operation, and
very low supply current, makes them an ideal choice for
battery-operated equipment and other low-voltage appli-
cations. The MAX492/MAX494/MAX495 are available in
DIP and SO packages in the industry-standard op-amp
pin configurations. The MAX495 is also available in the
smallest 8-pin SO: the μMAX package.
