MAX492/MAX494/MAX495 Precision Operational Amplifiers are low-voltage single-supply, rail-to-rail input and output operational amplifiers ideal for portable equipment, battery-powered instruments, data acquisition and signal conditioning applications.
This document describes the dual MAX492, quad MAX494, and single MAX495 operational amplifiers. These devices combine excellent DC accuracy with rail-to-rail input and output operation, allowing them to function from a single supply of +2.7V to +6V or split supplies up to +/-3V.
| Supply Voltage Range | +2.7V to +6V (Single) or +/-1.35V to +/-3V (Split) |
|---|---|
| Supply Current | < 150uA per Op Amp |
| Gain-Bandwidth Product | 500kHz |
| Input Noise Voltage Density | 25nV/sqrt(Hz) |
| Output Short-Circuit Current | 30 mA |
Each amplifier requires less than 150uA of supply current.
Yes, the devices are capable of driving a 1kQ load even with low supply current.
The input referred voltage noise is only 25nV/VHz.
