1. Describe

ISO124P is a precision isolation amplifier Incorporates a novel duty cycle modulation and demodulation technique. signal is transmitted Digitally cross a 2pF differential capacitive barrier. With digital modulation, the barrier characteristics are not without compromising signal integrity, resulting in excellent Reliability and good high frequency transient immunity Get over obstacles. Both barrier capacitors are Embedded in the encapsulated plastic body. ISO124 is easy to use. No external components required is required for operation. The key specs are 0.010% maximum nonlinearity, 50kHz signal bandwidth and 200µV/°C VOS drift. a power supply The range is ±4.5 V to ±18 V, and the quiescent current is ±5 mA on VS1 and ±5.5 mA on VS2 makes ISO124 The device is ideal for a wide range of applications. ISO124 is available in 16-pin PDIP and 28-pin SOIC plastic surface mount package.
