Writing to this field sets the DC Offset value for HPOUT1R

in DAC Write DC Servo mode.

Reading this field gives the current DC Offset value for

HPOUT1R.

Two’s complement format.

LSB is 0.25mV.

Range is -32mV to +31.75mV

Writing to this field sets the DC Offset value for HPOUT1L

in DAC Write DC Servo mode.

Reading this field gives the current DC Offset value for

HPOUT1L.

Two’s complement format.

LSB is 0.25mV.

Range is -32mV to +31.75mV

HPOUT1L_RMV

_SHORT

Removes HPOUT1L short

0 = HPOUT1L short enabled

1 = HPOUT1L short removed

For normal operation, this bit should be set as the final step

of the HPOUT1L Enable sequence.

HPOUT1L_OUT

Enables HPOUT1L output stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after the DC

offset cancellation has been scheduled.

HPOUT1L_DLY

Enables HPOUT1L intermediate stage

0 = Disabled

1 = Enabled

For normal operation, this bit should be set to 1 after the
