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 con-
