36V Radiation Tolerant Precision Instrumentation Amp
with Rail-to-Rail Output Differential ADC Driver
ISL70617SEH
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 (±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 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.
The gain of the ISL70617SEH can be programmed from 0.1 to
10,000 via two external resistors, R
IN
and R
FB
. The gain
accuracy is determined by the matching of R
IN
and R
FB
. The
gain resistors have Kelvin sensing, which removes gain error
due to PC 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.
The ISL70617SEH is offered in a 24 Ld ceramic flatpack
package with an operating temperature range of -55°C to
+125°C.
