  • Wheatstone Bridge with High Accuracy Instrumentation Amplifier

    Created by NiMultisimDesigner, published on 16-12-2012

    This circuit measures an unknown resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component, detecting the zero voltage with a multimeter when the balance is reached, with reference to this circuit when R1/R2 = R3/Rpot.The potential small voltage differences are amplified by a low power instrumentation amplifier AD620.

  • Time to Voltage Converter with OPA627E

    Created by TINADesigner, published on 23-12-2011

    Applications such as rangefinders and ballistic chronographs require a high resolution measurement of time. This can be a time period of a few hundred nanoseconds to a few milliseconds. This is an analog circuit, based on a OPA627E with dual power supply, that can convert a time period to a voltage with high linearity and high resolution

  • Laser Energy Meter

    Created by TINADesigner, published on 05-12-2011

    The IVC102 is a precision integrating amplifier with FET op amp, integrating capacitors, and low leakage FET switches, capable of integrating the output of a very fast detector. 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 IVC102 provides a precision, lower noise alternative to conventional transimpedance op amp circuits that require a very high value feedback resistor.
