Analog Devices / Maxim Integrated MAX492 Dual Micropower Op Amps

Analog Devices MAX492 Dual Micropower Op Amps combine excellent DC accuracy with rail-to-rail operation at the input and output. The common-mode voltage extends from VCC to VEE, allowing these Analog Devices op amps to operate from either a single supply (+2.7V to +6V) or split supplies (±1.35V to ±3V).

The MAX492 op amp requires less than 150μA supply current and can drive a 1kΩ load. The input referred voltage noise is only 25nV/√Hz, and these op-amps can drive loads over 1nF. The precision performance of the MAX492, combined with its wide input and output dynamic range, low-voltage single-supply operation, and very low supply current, makes it an ideal choice for battery-operated equipment and other low-voltage applications.
