Single/Dual/Quad, Micropower,
Single-Supply Rail-to-Rail Op Amps
_______________General Description
The 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 V
CC
to V
EE
,
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 1kΩ load, 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.
