AMC1210: Reading 2 data outputs

Tal Turgeman

Part Number: AMC1210

Hello,

I'm using AMC1210 to filter sigma-delta ADC for current sense application.

The AMC1210 has 4 filter modules , Is it possible to read 2 data module outputs at the same time?

Best regards,

Tal

    Hi Tal,

    By 'at the same time' if you are asking can you read two of the AMC1210 filter outputs simultaneously, the answer is no. You can synchronize filters though and read two, three or four filter outputs sequentially though - see Figure 12 on page 14 of the datasheet. The data registers are at address 1D, 1F, 21 and 23.

    Hi Tom,

    Thank you for your quick reply.
    what is the minimun time I'll have to wait between each address to the register map?

    Hi Tal,

    The timing limitations for serial mode are shown on page 7. The address to be read from or written to is decoded in the command byte so that by the 9th SCLK you are at the correct register. If you wanted to read through the Time Registers (and just ignore their content) you can do that by starting your read at address 1D and just keep clocking through - the address will automatically increment to the next register.
