Three OPAMP instrumentation amplifier

Version 1
    Question: Is there any instrumentation amplifier in PSoC1?



    Yes, PSoC1 analog blocks can be used to build two forms of instrumentation amplifier – Two OPAMPs and Three OPAMP topology. For both these forms, PSoC Designer provides user module- INSAMP which does the configuration of analog blocks to get an instrumentation amplifier.

    The attached document and project demonstrates how to use INSAMP user module in Three OPAMP mode. The project is designed to amplify external voltage using INSAMP and read the INSAMP output using ADC. The ADC result is then displayed on a character LCD.
