Preliminary specification
Universal Serial Bus (USB)
Digital-to-Analog Converter (DAC)
UDA1321
USB-DAC UDA1321/N101 (FIRMWARE SW 2.1.1.7)
The following items are different for the UDA1321/N101 compared to the general content of this data sheet:
Volume control
Treble control
Power management.
Table 10
Volume control characteristics
The treble control is available for the master channel of the UDA1321. Treble can be regulated in three modes: minimum,
flat and maximum mode. The preferred mode is selected via the configuration map. The corner frequency is 3000 Hz for
the minimum mode and 1500 Hz for the maximum mode. The treble range is from 0 to 6 dB (discrete steps
0, 4 and 6 dB). It should be noted that the negative treble values as defined in the “USB Device Class Definition for Audio
Devices”are not supported by the UDA1321; the 0 dB value is returned as 0 dB. Table 4 gives the mapping of the
bTreble
value upon the actual treble setting of the USB DAC.
