Maxim MAX44248 Operational Amplifiers

Maxim MAX44248 Operational Amplifiers provide very low-power operation with a wide supply range. These devices feature a patented auto-zero circuit that constantly measures and compensates the input offset to eliminate drift over time and temperature as well as the effect of 1/f noise. These devices also feature integrated EMI filters to reduce high-frequency signal demodulation on the output. The op amps operate from either a single 2.7V to 36V supply or dual ±1.35V to ±18V supply. The devices are unity-gain stable with a 1MHz gain-bandwidth product and a low 90µA supply current per amplifier. The low offset and noise specifications and high supply range make the Maxim MAX44248 ideal for sensor interfaces and transmitters.
