MAX494CSD

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

The dual MAX492, quad MAX494, and single MAX495 operational amplifiers combine excellent DC accuracy with rail-to-rail operation at the input and output. Since the common-mode voltage extends from VCCto 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 150µA supply current. Even with this low current, the op amps are capable of driving a 1kΩload, and the input referred voltage noise is only 25nV/√Hz. In addition, these op amps can drive loads in excess of 1nF.

The precision performance of the MAX492/MAX494/MAX495, combined with their wide input and output dynamic range, low-voltage single-supply operation, and very low supply current, makes them an ideal choice for battery-operated equipment and other low-voltage applications.

The MAX492/MAX494/MAX495 are available in DIP and SO packages in the industry-standard op-amp pin configurations. The MAX495 is also available in the smallest 8-pin SO: the µMAX package.
