Bit Name
Description
DB0
C0
C0 = 0: the device is not in thermal shutdown mode.
C0 = 1: the device is in thermal shutdown mode.
DB1
C1
C1 = 0: reserved. This bit should be 0 when writing to the control register.
DB2
C2 = 0: DAC Channel A power-down (default).
C2 = 1: DAC Channel A power-up.
DB3
C3 = 0: DAC Channel B power-down (default).
C3 = 1: DAC Channel B power-up.
DB4
C4 = 0: DAC Channel C power-down (default).
C4 = 1: DAC Channel C power-up.
DB5
C5 = 0: DAC Channel D power-down (default).
C5 = 1: DAC Channel D power-up.
DB6
C6
C6 = 0: outputs connected to AGND through a 20 k resistor (default).
C6 = 1: outputs are three-stated.
1
If Bit C2 to Bit C5 are set to 0, the part is placed in power-down mode.
