Single/Dual/Quad, Micropower, Single-Supply, Rail-to-Rail Op Amps MAX4091/MAX4092/MAX4094 General Description Features
The single MAX4091, dual MAX4092, and quad ♦
Low-Voltage, Single-Supply Operation (2.7V to 6V)
MAX4094 operational amplifiers combine excellent DC accuracy with Rail-to-Rail® operation at the input and ♦

output. Since the common-mode voltage extends from ♦
No Phase Reversal for Overdriven Inputs
VCC to VEE, the devices can operate from either a sin- gle supply (2.7V to 6V) or split supplies (±1.35V to ♦
30µV Offset Voltage
±3V). Each op amp requires less than 130µA of supply ♦

voltage noise is only 12nV/√Hz. In addition, these op ♦
165µA (max) Quiescent Current Per Op Amp
amps can drive loads in excess of 2000pF. ♦
500kHz Gain-Bandwidth Product
The precision performance of the MAX4091/MAX4092/ MAX4094 combined with their wide input and output ♦
High Voltage Gain (115dB)
dynamic range, low-voltage, single-supply operation, ♦
High Common-Mode Rejection Ratio (90dB) and
and very low supply current, make them an ideal choice for battery-operated equipment, industrial, and

data acquisition and control applications. In addition, ♦
Temperature Range (-40°C to +125°C)
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
