MAX44248

EVALUATION KIT AVAILABLE MAX44248 36V, Precision, Low-Power, 90µA, Dual Op Amp General Description The MAX44248 is an ultra-precision, low-noise, zero-drift dual operational amplifier featuring very low-power operation with a wide supply range. The device incorporates 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. The device also features integrated EMI filters to reduce high-frequency signal demodulation on the output. The op amp operates from either a single 2.7V to 36V supply or dual ±1.35V to ±18V supply. The device is 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 device ideal for sensor interfaces and transmitters. The device is available in 8-pin FMAXM and SO packages and is specified over the -40NC to +125NC automotive operating temperature range.
