December 15, 2016 36V Radiation Tolerant Precision Instrumentation Amplifier with Rail-to-Rail Output
ADC Driver Features The ISL70517SEH is a high performance, differential input,
single-ended 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 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 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. Rail-to-rail single-ended output ADC driver Low input offset .30ВµV Input bias current . 0.2nA Excellent CMRR and PSRR 120dB Wide operating voltage range .

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 …
