ISO100 is an optocoupler isolation amplifier. The LED generates coupled light, and the coupled light is negatively fed back to the input terminal and transmitted forward to the output terminal at the same time, achieving high accuracy, linearization and long-term temperature stability. Fine matching of the optocoupler and the use of laser correction on the amplifier ensure its excellent tuning performance and low offset error. ISO100 can be used as a current-voltage converter with a minimum voltage of 750V (2500V test voltage) between its input and output, effectively breaking the connection between the input and output of the common current, with ultra-low leakage current, The maximum leakage current is 0.3μA at 240V and 60Hz. Input voltage operation can be easily realized with an external resistor. The outstanding DC and AC performance of ISO100 and its versatility enable it to provide an excellent solution when solving complex isolation problems. For example, ISO100 has the ability to work in many modes, including in-phase (unipolar and bipolar) and anti-in-phase (unipolar and bipolar) configurations, and two precision current sources can achieve bipolar operation. Because in these occasions that do not need a single power supply to work, using ISO100 to design the circuit, almost no external components can be used. The output voltage Vout can be easily determined by IIN×RF, and the change in gain can be determined by changing a resistance value. In addition, ISO100 has enough bandwidth to amplify the signals of most industrial and test instruments.
