DAC Control - Address 03h
Power-Down DAC (Bit 1)
Function:
The DAC pair will remain in a reset state whenever this bit is set.
Power-Down Device (Bit 0)
Function:
The device will enter a low-power state whenever this bit is set. The power-down bit is set by default and
must be cleared before normal operation can occur. The contents of the control registers are retained
when the device is in power-down.
DAC Digital Interface Format (Bits 5:4)
Function:
The required relationship between LRCK, SCLK and SDIN for the DAC is defined by the DAC Digital In-
terface Format and the options are detailed in
Mute DAC (Bit 2)
Function:
The DAC outputs will mute and the MUTEC pin will become active when this bit is set. Though this bit is
active high, it should be noted that the MUTEC pin is active low. The common mode voltage on the outputs
will be retained when this bit is set. The muting function is effected, similar to attenuation changes, by the
DACSoft and DACZero bits in the DAC Control 2 register.
