Intrduction
The ISO103 isolation amplifier provides both signal and power across an isolation barrier. The ceramic non-hermetic hybrid package with side-brazed pins contains a transformer-coupled DC/DC converter and
a capacitor-coupled signal channel.
Extra power is available on the isolated input side for external input conditioning circuitry. The converter is protected from shorts to ground with an internal current limit, and the soft-start feature limits the initial currents from the power source. Multiple-channel synchronization can be accomplished by applying a TTL clock signal to paralleled Sync pins. The Enable control is used to turn off transformer drive while keeping the signal channel demodulator active. This feature provides a convenient way to reduce quiescent current for low power applications.
The wide barrier pin spacing and internal insulation allow for the generous 1500Vrms continuous rating. Reliability is assured by 100% barrier breakdown testing that conforms to UL1244 test methods. Low
barrier capacitance minimizes AC leakage currents.
These specifications and built-in features make the ISO103 easy to use, as well as providing for compact PC board layouts.
