AMC7834: Chip is not responding for the read operation.

Part Number: AMC7834


After power on AMC chip we are doing read operation  for the register(0x0C). When giving the command as per the spec (SDO) 0x8C(8 denotes the read operation and C is the address) is given to chip but device is not responding. 

We are providing the clock in the above pattern like there is a gap between the clock cycles but the CS pin is asserted low during the entire operation. Our concern is though there is a delay between the clock pulses due to that device is not providing the response for the chip.  If we give the clock pulse in this pattern will the chip will respond ? Please let me know the concerns.

How the write and read  pattern should to get the correct response. Any procedure is there after power on the chip. 

  • Hi Siva,

    Can you confirm that the clock phase and polarity is correct? Can you confirm that the device is powered on and operation? You could try some write commands to change a DAC to confirm if you have correct writing capability.
