MAX44244/MAX44245/ 36V, Precision, Low-Power, 90A, MAX44248 Single/Quad/Dual Op Amps General Description Benefits and Features The MAX44244/MAX44245/MAX44248 family of parts Reduces Power for Sensitive Precision Applications provide ultra-precision, low-noise, zero-drift single/quad/ Low 90A Quiescent Current per Amplifier dual operational amplifiers featuring very low-power Eliminates the Cost of Calibration with Increased operation with a wide supply range. The devices Accuracy with Maxims Patented Autozero Circuitry incorporate a patented auto-zero circuit that constantly Very Low Input Voltage Offset 7.5V (max) measures and compensates the input offset to eliminate Low 30nV/C Offset Drift (max) drift over time and temperature as well as the effect of 1/f Low Noise Ideal for Sensor Interfaces and noise. These devices also feature integrated EMI filters Transmitters to reduce high-frequency signal demodulation on the output. The op amps operate from either a single 2.7V to 50nV/Hz at 1kHz 36V supply or dual 1.35V to 18V supply. The devices 0.5V from 0.1Hz to 10Hz P-P are unity-gain stable with a 1MHz gain-bandwidth product 1MHz Gain-Bandwidth Product and a low 90A supply current per amplifier. EMI Suppression Circuitry The low offset and noise specifications and high supply Rail-to-Rail Output range make the devices ideal for sensor interfaces and Wide Supply for High-Voltage Front Ends transmitters. 2.7V to 36V Supply Range , SO, SOT23, and The devices are available in MAX MAX, SO, SOT23, TSSOP Packages TSSOP packages and are specified over the -40C to +125C automotive operating temperature range.
