MAX4091ASA+T

The MAX4091ASA+T is a single operational amplifier from Analog Devices / Maxim Integrated, part of a series that includes dual and quad configurations. It is designed for low-voltage, single-supply operation, functioning with supply voltages ranging from 2.7V to 6V, or split supplies from ±1.35V to ±3V. This op-amp features Rail-to-Rail input and output swing, making it suitable for applications where maximizing dynamic range is critical.

Key electrical characteristics include a 500kHz gain-bandwidth product, a low quiescent current of 165µA per op-amp, and a high voltage gain of 115dB. It also boasts a low offset voltage of 30µV and input-referred voltage noise of 12nV/√Hz. The device is unity-gain stable with loads up to 2000pF and can drive a 1kΩ load.

With an operating temperature range of -40°C to +125°C, the MAX4091ASA+T is well-suited for battery-operated equipment, industrial controls, and data acquisition systems. It is available in space-saving packages such as SOT23-5, 8-pin µMAX, and 8-pin SO.

Applications include portable equipment, battery-powered instruments, data acquisition and control, and low-voltage signal conditioning. The precision performance and low power consumption make it an ideal choice for various embedded systems.
