ISL70617SEH FN8697
Rev 4.00
December 16, 2016 36V Radiation Tolerant Precision Instrumentation Amp with Rail-to-Rail Output
Differential ADC Driver Features The ISL70617SEH is a high performance, differential input,
differential output instrumentation amplifier designed for
precision analog-to-digital applications. It can operate over a
supply range of 8V (В±4V) to 36V (В±18V) and features a
differential input voltage range up to В±30V. The output stage
has rail-to-rail output drive capability optimized for differential
ADC driver applications. The output stage is powered by
separate supplies. This feature enables the output to be driven
by the same low voltage supplies powering the ADC, thereby
providing protection from high voltage signals and the low
voltage digital circuits. Its versatility makes it suitable for a
variety of general purpose applications. Additional features not
found in other instrumentation amplifiers enable high levels of
DC precision and excellent AC performance.

10,000 via two external resistors, RIN and RFB. The gain
accuracy is determined by the matching of RIN and RFB. The
gain resistors have Kelvin sensing, which removes gain error …
