GENERAL DESCRIPTION The AD8227 is a lo w cost, wide supply range instrumentati on amplifier that requires only one ext ernal resistor to set any gain between 5 and 1000. The AD8227 is designed to w ork with a variety of signal voltages. A wide input range and rail-to-rail out put allow the signal to make full use o f the supply rails. Because the input r ange can also go below the negative sup ply, small signals near ground can be a mplified without requiring dual supplie s. The AD8227 operates on supplies rang ing from ±1.5 V to ±18 V (2.2 V to 36 V single supply). The robust AD8227 in puts are designed to connect to realwor ld sensors. In addition to its wide ope rating range, the AD8227 can handle vol tages beyond the rails. For example, wi th a ±5 V supply, the part is guarante ed to withstand ±35 V at the input with no damage.
