Precision, Powered, Three-Port Isolated
INSTRUMENTATION AMPLIFIER
DESCRIPTION
ISO255 is a precision three-port isolated instrumenta-
tion amplifier incorporating a novel duty cycle modu-
lation-demodulation technique and has excellent accu-
racy. 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 character-
istics 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.
A power supply range of 11V to 18V makes this
amplifier ideal for a wide range of applications.
