The ISO124 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 ISO124 is easy to use. No external components are required for operation. The key specifications are 0.010% maximum nonlinearity, 50-kHz signal bandwidth, and 200-µV/°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 ISO124 device ideal for a wide range of applications.
●The ISO124 is available in SOIC-16 and SOIC-28 plastic surface-mount packages.
