The MAX4091AUK+T is a single, micropower, single supply, rail to rail op-amp in 5 pin SOT-23 package. The operational amplifier combines excellent DC accuracy with rail to rail operation at the input and output. Since the common mode voltage extends from VCC to VEE, the device can operate from either a single 2.7V to 6V supply or split supplies ±1.35V to ±3V. The op-amp requires less than 130μA of supply current. Even with the low current, the op-amp is capable of driving a 1Kohm load and the input referred voltage noise is only 12nV/√Hz. In addition, this op-amp can drive loads in excess of 2000pF. The precision performance of the MAX4091 combined with their wide input and output dynamic range, low voltage, single supply operation and low supply current make it an ideal choice for battery operated equipment, industrial and data acquisition and control applications.
