ISO124U/1K
3 Description The ISO124 is a precision isolation amplifier incorporating a novel duty cycle modulationdemodulation 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 a good choice for a wide range of applications. The ISO124 is available in 16-pin PDIP,

The sense amplifier detects the signal transitions across the capacitive barrier and drives a switched current source into integrator A2. The output stage balances the duty-cycle modulated current against the feedback current through the 200-kΩ feedback resistor, resulting in an average value at the VOUT pin equal to VIN. The sample-and-hold amplifiers in the output feedback loop serve to remove undesired ripple voltages inherent in the demodulation process. 深圳市跃创芯科技有限公司,
