MAX4092AUA

单/双/四路，微功耗，单电源，轨至轨运算放大器 Single/Dual/Quad, Micropower, Single-Supply, Rail-to-Rail Op Amps

General Description

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.
