Single/Dual/Quad, Micropower, Single-Supply, Rail-to-Rail Op Amps
General Description
T h e single MAX4091, dual MAX4092, and quad MAX4094 operational amplifiers combine excellent DC accuracy with Rail-to-Rail® operation at the input and output. Since the common-mode voltage extends from VCC to VEE, the devices can operate from either a sing l e 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 1k 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, a n d 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. o Beyond-the-RailsTM Inputs o No Phase Reversal for Overdriven Inputs o 30µV Offset Voltage o Rail-to-Rail Output Swing with 1k Load o Unity-Gain Stable with 2000pF Load o 165µA (max) Quiescent Current Per Op Amp o 500kHz Gain-Bandwidth Product o High Voltage Gain (115dB) o High Common-Mode Rejection Ratio (90dB) and Power-Supply Rejection Ratio (100dB) o Temperature Range (-40°C to +125°C)

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.
