AMC1305M25, AMC1305L25 - the max and min vaule of VClipping

Other Parts Discussed in Thread: AMC1305L25, AMC1305M25

Hi all

Would you mind if we ask AMC1305M25 and AMC1305L25?

How much are the max and the min vaule of VClipping of AMC1305M25 and AMC1305L25?
We guess that you don't define these vaules.
If you have some reference data, could you let us know?
(Our customer will use these as reference datas.)

Kind regards,

Hirotaka Matsumoto

    Hi Hirotaka-san,

    The MIN and MAX values for clipping on the AMC1305 will depend on the offset. The clipping parameter is not production tested which is why it's only listed as a typical number. The linear operating range of the AMC1305M25 is +/-250 mV and you will see the behavior described in Figure 52 once the inputs are saturated (clipping).

    Thank you for your reply always!

    If it is possible to reply, or could you give us some advice about the following?

    <Content>
    -Input=250mV
    How much is the conversion vaule? XXXd(±△△)  (△△ means tolerance), (XXX means decimal data)
    Or, our customer would like to know output pulse(%) as the following;
    For example) typ : (250mV + 312.5mV) / (2 x 312.5mV) = 90% →　90% x 65535d = 58981d

    We appreciate your help.

    Kind regards,

    Hirotaka Matsumoto

    Hi Matsumoto-san,

    The output one's density is going to be as you described, but the word size (decimal value) is going to be dependent on the type and order of digital filter that you apply to the output bit stream. Take a look at this application note for further detail:
