The ISL28617SMR25EV1Z, ISL28617SM10EV1Z and ISL28617SM100EV1Z evaluation boards are designed to assess the performance of the ISL28617 differential input, differential output, precision instrumentation amplifier (in-amp). With an input voltage range up to ±34V, a supply voltage range of 8V (±4V) to 40V (±20V) and a gain ranging from 0.1 to 10,000, this in-amp is ideal for a wide variety of applications. The gain accuracy is limited only by the matching of the gain resistors, and the output is capable of driving rail-to-rail.
