The single MAX4091, dual MAX4092, and quad
MAX4094 operational amplifiers combine excellent DC
accuracy with Rail-to-Rail
output. Since the common-mode voltage extends from
V
gle supply (2.7V to 6V) or split supplies (±1.35V to
±3V). Each op amp requires less than 130µA of 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 12nV/√Hz. In addition, these op
amps can drive loads in excess of 2000pF.
The precision performance of the MAX4091/MAX4092/
MAX4094 combined with their wide input and output
dynamic range, low-voltage, single-supply operation,
and very low supply current, make them an ideal
choice for battery-operated equipment, industrial, and
data acquisition and control applications. In addition,
the MAX4091 is available in space-saving 5-pin SOT23,
8-pin µMAX, and 8-pin SO packages. The MAX4092 is
available in 8-pin µMAX and SO packages, and the
MAX4094 is available in 14-pin TSSOP and 14-pin SO
packages.
