These devices also feature integrated EMI filters Transmitters to reduce high-frequency signal demodulation on the 50nV/Hz at 1kHz output. The op amps operate from either a single 2.7V to 0.5V from 0.1Hz to 10Hz P-P 36V supply or dual 1.35V to 18V supply. The devices 1MHz Gain-Bandwidth Product are unity-gain stable with a 1MHz gain-bandwidth prod- EMI Suppression Circuitry uct and a low 90A supply current per amplifier. Rail-to-Rail Output The low offset and noise specifications and high supply Wide Supply for High-Voltage Front Ends range make the devices ideal for sensor interfaces and 2.7V to 36V Supply Range transmitters. MAX, SO, SOT23, TSSOP Packages The devices are available in FMAXM, SO, SOT23, and TSSOP packages and are specified over the -40NC to +125NC automotive operating temperature range.
