精度低成本隔离放大器
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 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.
