DESCRIPTION
The ISO113 output isolation amplifier provides both
signal and output power across an isolation barrier in
a small double-wide DIP package. The ceramic non-
hermetic hybrid package with side-brazed pins con-
tains a transformer-coupled DC/ DC converter and a
capacitor-coupled signal channel.
Extra power is available on the isolated output side for
driving external loads. 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 modulator 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
ISO113 easy to use, and provides for compact PC
board layout.
