The TPA1286 is a low cost, wide supply range instrumentationamplifier that requires only one external resistor to set any gainbetween 1 and 1,000. The TPA1286 is designed to work witha variety of single voltages. A wide input range and rail-to-railoutput allow the signal to make full use of the supply rails. Lowvoltage offset, low offset drift, low gain drift, high gainaccuracy, and high CMRR make this part an excellent choicein applications that demand the best DC performance.The TPA1286 operates from single 4V to 36V supply, offersbreakthrough performance throughout the −40°C to +125°Ctemperature range. It features a zero-drift core, which leads toa typical offset drift of 0.2μV/°C throughout the operatingtemperature range.TPA1286 is available in SOP8, MSOP8 and DFN3X3-8 package.
