36V Radiation Hardened Precision Instrumentation Amplifier with Rail-to-Rail
Output ADC Driver
The ISL70517SEH is a high performance, differential input,
Features
single-ended output instrumentation amplifier designed for
• Rail-to-rail single-ended output ADC driver
precision analog-to-digital applications. It can operate over a
supply range of 8V (±4V) to 36V (±18V) and features a
differential input voltage range up to ±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.

The gain of the ISL70517SEH can be programmed from 0.1 to
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
due to PCB trace resistance. The input and output stages have
individual power supply pins, which enable input signals riding
on a high common-mode voltage to be level-shifted to a low
voltage device, such as an A/D converter. The rail-to-rail output
stage can be powered from the same supplies as the ADC,
which preserves the ADC maximum input dynamic range and
eliminates ADC input overdrive.
Applications
• ADC driver
• Precision test and measurement
• High voltage process control
• Signal conditioning for remote powered sensors
• Satellite communication
The ISL70517SEH is offered in a 24 Ld ceramic flatpack
package with an operating temperature range of -55°C to
+125°C.
