DESCRIPTION
ISO175 is a precision isolated instrumentation ampli-
fier incorporating a novel duty cycle modulation-
demodulation technique and excellent accuracy. A
single external resistor sets the gain. Internal input
protection can withstand up to ±40V without damage.
The signal is transmitted digitally across a differential
capacitive barrier. With digital modulation the barrier
characteristics do not affect signal integrity. This re-
sults in excellent reliability and good high frequency
transient immunity across the barrier. Both the ampli-
fier and barrier capacitors are housed in a plastic DIP.
ISO175 is easy to use. A power supply range of ±4.5V
to ±18V makes this amplifier ideal for a wide range of
applications.
