    Hi,

    Am building an heart sound amplifier. Currently am confused between the following OPAMPs

    1. OPA2314
    2. OPA2132

    While the former is known for low-noise applications the latter is high precision and has a very high CMRR.

    I need all these qualities in the amplifier. I have simulation-tested both the OPAMP on Proteus-7 and both seem to give a good performance under the simulation.

    Next stage is to fabricate the circuit and I want to be dead sure of which OPAMP to go ahead with.
