Description

ISO254 is a precision three-port isolated programmable 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 components are required. A power supply range of 11V to 18V makes this amplifier ideal for a wide range of applications.
