ISO165 and ISO175 are precision isolated instrumentation
amplifiers 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 results in excellent reliability and good high
frequency transient immunity across the barrier. Both
the amplifier and barrier capacitors are housed in a
plastic DIP. ISO165 and ISO175 differ in frequency
response and linearity.
These amplifiers are easy to use. A power supply
range of ±4.5V to ±18V makes these amplifiers ideal
for a wide range of applications.
