Product Summary

The IVC102U is a precision integrating amplifier with FET op amp, integrating capacitors, and low leakage FET switches. It integrates low-level input current for a user-determined period, storing the resulting voltage on the integrating capacitor. The output voltage can be held for accurate measurement. The IVC102U provides a precision, lower noise alternative to conventional transimpedance op amp circuits that require a very high value feedback resistor. The applications of the IVC102U include precision low current measurement, photodiode measurements, ionization chamber measurements, current/charge-output sensors, leakage current measurement.
