Product Summary

The MAX494CSD is a quad operational amplifier. It 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 MAX494CSD 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 MAX494CSD is capable of driving a 1kΩ load, and the input referred voltage noise is only 25nV/Hz. In addition, the op amp can drive loads in excess of 1nF. The applications of the MAX494CSD include Portable Equipment, Battery-Powered Instruments, Data Acquisition, Signal Conditioning and Low-Voltage Applications.
