MAX44244

EVALUATION KIT AVAILABLE MAX44244/MAX44245/MAX44248 36V, Precision, Low-Power, 90µA, Single/Quad/Dual Op Amps General Description The MAX44244/MAX44245/MAX44248 family of parts provide ultra-precision, low-noise, zero-drift single/quad/ dual operational amplifiers featuring very low-power operation with a wide supply range. The devices incorporate 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 devices ideal for sensor interfaces and transmitters. The devices are available in FMAXM, SO, SOT23, and TSSOP packages and are specified over the -40NC to +125NC automotive operating temperature range.
