DESCRIPTION
The ISO122 is a precision isolation amplifier incor-
porating a novel duty cycle modulation-demodulation
technique. The signal is transmitted digitally across
a 2pF differential capacitive barrier. With digital modu-
lation the barrier characteristics do not affect signal
integrity, resulting in excellent reliability and good high
frequency transient immunity across the barrier. Both
barrier capacitors are imbedded in the plastic body of
the package.
The ISO122 is easy to use. No external components
are required for operation. The key specifications are
0.020% max nonlinearity, 50kHz signal bandwidth,
and 200µV/°C V
OS
drift. A power supply range of
±4.5V
to
±18V
and quiescent currents of
±5.0mA
on
V
S1
and
±5.5mA
on V
S2
make these amplifiers ideal
for a wide range of applications.
The ISO122 is available in 16-pin plastic DIP and 28-
lead plastic surface mount packages.
