Other Parts Discussed in Thread: TLC272

I want to simulate a circuit made by TLC272, when I choose TLC272 from TINA, it only can show the first channel,like Pin 1,2,3,4,8, who can tell me how to choose another part ,Pin 5,6,7?Because TLC 272 have double channel.Thanks very much!

    TINA macromodels are written for only a single amplifier, whether it be a single, dual, or quad op amp. The performance of each device within a package will be the same so duals and quads can be simulated by using 2 single devices or 4 devices in the case of a quad.

    Thans very much Neil , I have little experience on Analog design, Recently I am trying to learn some knowledge about Fliters, although there are plenty of instructions on Web, but I can not distinguish which is better.So could you give me some advice or recommend some martrials for me ?Thanks in advance.

    Xi;

    Filter choice depends entirely on your application-- what you are trying to accomplish with the filter. The higher order the filter, the sharper its cutoff (attenuation slope) or skirts will be. The type of filter -- Butterworth, Bessel, Chebycheff, etc determine mainly the characteristics in the bandpass-- the ripple, transient response (ringing), transitional response, and phase.

    If you can provide more details I could be more specific in my recommendations.
