40V Precision Instrumentation Amplifier with Differential A/D Converter Driver Evaluation Board


The ISL28617SMxxEV1Z evaluation board is 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 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.
