REGISTER DEFINITIONS
R/W
Read/Write Mode Select
When R/W = 0, a Write operation is performed.
When R/W = 1, a Read operation is performed.
Default Value: 0
ATx[7:0]
Digtial Attenuation Level Setting
Where x = 1 or 2, corresponding to the DAC output VOUTL (x = 1) and VOUTR (x = 2).
These bits are Read/Write.
Default Value: 1111 1111B
Each DAC output (VOUTL and VOUTR) has a digital attenuator associated with it. The attenuator may be set from
0dB to –63dB, in 0.5dB steps. Alternately, the attenuator may be set to infinite attenuation (or mute).
The attenuation data for each channel can be set individually. However, the data load control (ATLD bit of
Control Register 18) is common to both attenuators. ATLD must be set to ‘1’ in order to change an attenuator’s
setting. The attenuation level may be set using the following formula:
Attenuation Level (dB) = 0.5dB (ATx[7:0]DEC – 255)
Where: ATx[7:0]DEC = 0 through 255
For: ATx[7:0]DEC = 0 through 128, the attenuator is set to infinite attenuation.
The following table shows attenuator levels for various settings:
