Product Summary

The MAX494ESD operational amplifier combines 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. Each op amp requires less than 150μA supply current. Even with this low current, the op amps are capable of driving a 1k. load, and the input referred voltage noise is only 25nV/AHz. In addition, these op amps can drive loads in excess of 1nF. The precision performance of the MAX494ESD, 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 MAX494ESD is available in DIP and SO packages in the industry-standard op-amp pin configurations. The MAX494ESD is also available in the smallest 8-pin SO: the μMAX package.
