Description

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 VOSdrift. A power supply range of 4.5 V to 18 V and quiescent currents of 5 mA on VS1and ±5.5 mA on VS2make the ISO122 ideal for a wide range of applications. The ISO122 is available in 16-pin plastic DIP and28-lead plastic surface-mount packages.
