AMC7836: DAC Monitor

Part Number: AMC7836
Other Parts Discussed in Thread: AMC7834, , AFE10004

Hi, In Datasheet it is provided that the ADC pins can be used to monitor the DAC channels, can the ADC configure the DAC based on the monitored data or the ADC can only send the monitored data to an master

  • Hi Feshan,

    The AMC7836 does not have a "closed-loop" operation.  It will require a host controller to interpret the ADC data and set the DACs.  We have a few devices that do support closed loop operation.  The AMC7834 has 4 current shunt inputs that can be used to maintain a constant IDQ.  The AFE10004 can have a pre-programmed temperature compensation curve for PA biasing as well.
