  17000043 - ADC Reference Voltages Do Not Match Specification:

DESCRIPTION:

The ADC reference voltages (VREF0, VREF1, and VREF2) are not calibrated to the specified 2.5 V.

WORKAROUND:

Use the actual ADC reference voltage values in ADC calculations, not the specified value.

APPLIES TO REVISION(S):

0.0

9.

  17000044 - DAC Output Current Limit Is Less Than Specified:

DESCRIPTION:

The maximum DAC output current load specification is 5 mA. The actual DAC output current load is limited to 1 mA.

WORKAROUND:

None.

APPLIES TO REVISION(S):

0.0

10.

  17000046 - ADC Auxiliary Bypass Mode Cannot Be Cleared By Register Write:

DESCRIPTION:

The auxiliary bypass bit cannot be cleared by a register write. If the ADC is set to enter auxiliary buffer bypass mode during operation, it
cannot subsequently be reverted to non-bypass mode.

WORKAROUND:

If the auxiliary bypass bit is set, a soft reset is required to take the AFE out of auxiliary buffer bypass mode. The ADCC drivers include the

adi_adcc_SetRegister()

 function to communicate with the AFE through the ADCC module. The ADCC drivers are furnished in the

EVAL-CM41X-EZBRD/EZLITE evaluation platform Board Support Package (BSP).

The following is an example to issue the soft reset to the Analog Front End:

 #include <drivers/adcc/adi_adcc.h>
 ADI_ADCC_HANDLE handle;
 ADI_ADCC_RESULT result;
 static char space[ADI_ADCC_MEMORY];
 
 result = adi_adcc_Open(0, space, &handle, false);
 result = adi_adcc_SetRegister(handle, REG_USER_CONFIG_REG0_USERCFG, 0x00400000);
 if (result == ADI_ADCC_SUCCESS) 
 {
    /* Success! */
 } 
 else 
 {
    /* Failure! */
 }
 

For more information about the APIs, refer to Device Driver documentation and example codes in the Board Support Package (BSP).
