Precision, Powered, Three-Port Isolated
PROGRAMMABLE GAIN AMPLIFIER
DESCRIPTION
ISO254 is a precision three-port isolated program-
mable gain instrumentation amplifier incorporating a
novel duty cycle modulation-demodulation technique
and has excellent accuracy. Internal input protection
can withstand up to
±
40V input differential 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. The
DC/DC converter, amplifier and barrier capacitors are
housed in a plastic DIP.
This amplifier is easy to use as no external compo-
nents are required. A power supply range of 11V to
18V makes this amplifier ideal for a wide range of
applications.
