DESCRIPTION
The ISO124 is a precision isolation amplifier incorporating a
novel duty cycle modulation-demodulation technique. The
signal is transmitted digitally across a 2pF differential capacitive
barrier. With digital modulation, 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 ISO124 is easy to use. No external components are
required for operation. The key specifications are 0.010%
max nonlinearity, 50kHz signal bandwidth, and 200μV/°C
VOS drift. A power supply range of ±4.5V to ±18V and
quiescent currents of ±5.0mA on VS1 and ±5.5mA on VS2
make these amplifiers ideal for a wide range of applications.
The ISO124 is available in DIP-16 and SO-28 plastic surface
mount packages.
