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.
