Product Details
The 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 single 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.
