The ISO122 is a precision isolation amplifier incorporating a novel duty cycle modulation-demodulation technique. The signal is transmitted digitally across a 2-pF differential capacitive barrier. With digital modulation the barrier characteristics do not affect signal integrity, thus 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% maximum nonlinearity, 50-kHz signal bandwidth, and 200-V/°C VOS drift. A power supply range of 4.5 V to 18 V and quiescent currents of 5 mA on VS1 and ±5.5 mA on VS2 make the ISO122 ideal for a wide range of applications.
●The ISO122 is available in 16-pin plastic DIP and 28-lead plastic surface-mount packages.
