TPA1286U-SO1R Instrumentation Amplifiers(3PEAK)

The TPA1286U-SO1R is a low cost,wide supply range instrumentation amplifier that requires only one external resistor to set any gain between 1 and 1,000.The TPA1286U-SO1R is designed to work with a variety of single voltages.A wide input range and rail-to-rail output allow the signal to make full use of the supply rails.Low voltage offset,low offset drift,low gain drift,high gain accuracy,and high CMRR make this part an excellent choice in applications that demand the best DC performance.

The TPA1286U-SO1R operates from single 4V to 36V supply,offers breakthrough performance throughout the−40°C to+125°C temperature range.It features a zero-drift core,which leads to a typical offset drift of 0.2μV/°C throughout the operating temperature range.

TPA1286U-SO1R is available in SOP8,MSOP8 and DFN3X3-8 package.
