DESCRIPTION
The ISO107 isolation amplifier provides both signal
and power across an isolation barrier. The ceramic
side-brazed hybrid package 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 cur-
rent limit, and the soft-start feature limits the initial
currents from the power source. Multiple-channel syn-
chronization can be accomplished by applying a TTL
clock signal to paralleled Sync pins. The Enable con-

trol 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 2500Vrms continuous rating.
Reliability is assured by 100% barrier breakdown
testing that conforms to UL544 test methods. Low
barrier capacitance minimizes AC leakage currents.
These specifications and built-in features make the
ISO107 easy to use, as well as providing for compact
PC board layouts.
