LMV1032 Gain Comparison

Other Parts Discussed in Thread: LMV1032

Hi team,

I see we have three versions of the LMV1032, providing different gains. Could you go over the advantages and disadvantages of using each of these (i.e. why would we not want a higher gain amplifier, what are some of the drawbacks, etc)?

Thank you,

Akash Patel

    Hi Akash

    The next table shows the parameters more important of the ICs.

      Devices  
    Parameters LMV1032-06 LMV1032-15 LMV1032-25 Units
    SNR  58 61 61 dB
    PSRR 75 70 65 dB
    Vin(Max) 300 170 60 mVpp
    Vout 300 500 600 mV
    THD 0.11 0.13 0.35 %

    You can observe that LMV1032-06 has best PSRR and THD, but worst SNR. All these parameters indicate that LMV1032-06 rejects a little best the noise. Also, you should take in account to select a device the application, for example, If you use LMV1032-25 and input receives a signal of 100mVpp, the device's output will get clicking(saturation), you would need to use LMV1032-15 because its Vin(Max) is 170mVpp.Lastly, you take in account the output signal level that you want to get.

    Please let me know your opinion or if you have more questions.

    Best regards
