Overview
19-0265; Rev 2; 9/96 Single/Dual/Quad, Micropower, Single-Supply Rail-to-Rail Op Amps _______________General Description 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 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 150µA 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 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.
