    Hi Reader,

    I want a absolute, high impedance differential amplifer with single supply. Does anybody know IC which works on +5V, gives |V1-V2| with offset of few tens micovolts and temp coeff of few µvolts/°C. Common mode voltage is +2.5V.

    I searched liner, ti but could not find.

    Thankds in advance.

    Indeed, Instrumentation amplifiers are actually considered a "unique" op amp. They both have facets that are very similar. You can actually aqcuire "A Designer's Guide to Instrumentation Amplifiers" from Analog Devices for free! Just type it in on the search bar on their website and register with them.
