I want to use LMP8100A(PGA) in our board. I want simulate the same circuit in TINA, But I didn't get the TINA model for that PGA. Can anyone help me..

Thanks in advance.

    Mani,

    Apologize for the delay. I noticed that the LMP81000 is at lifetime buy (LIFEBUY) and therefore is not recomended for new or long term designs.

    Have you looked at the PGA112 instead? Similar gain settings though it doesn't seem that there is a model for this PGA either. Is there a specific parameter or feature that you are interested in that maybe we can help provide more insight?

    PGA112,  typical -3db frequency is 1.6mhz at binary gain of 16v/v, it is too low.

    could you tell me another?

    my application,

    operation frequency is from 1mhz to 9mhz,

    I require the the gain about -10v/v to 16v/v.

    I need one channel.

    I need a programmable gain, logic port or spi is ok.

    Thanks you.

    Hello,

    Unfortunately we do not have such a device within the precision PGA catalog. However, you may consider the THS7001, a high-speed PGA with gain from -22 to +20dB and small-signal bandwidth of up to 100 MHz.
