APPLICATIONS
ISO166 and ISO176 are precision isolation amplifiers
incorporating an uncommitted operational amplifier
for input conditioning, a novel duty cycle modulation-
demodulation technique and excellent accuracy. Inter-
nal input protection can withstand up to ±30V differ-
ential without damage. The signal is transmitted digi-
tally across a differential capacitive barrier. With digi-
tal 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. ISO166 and ISO176 differ in
frequency response and linearity.
These amplifiers are easy to use. No external compo-
nents are required. A power supply range of ±4.5V to
±18V makes these amplifiers ideal for a wide range of
applications.
