input data rate.
1.3
DAC digital sound processing
The UDA1334TS supports the I
2
S-bus data format with
word lengths of up to 24 bits and the LSB-justified serial
data format with word lengths of 16, 20 and 24 bits.
The UDA1334TS has basic features such as de-emphasis
(at 44.1 kHz sampling rate) and mute.
•
Digital de-emphasis for 44.1 kHz sampling rate
•
Mute function.
1.4
Advanced audio configuration
•
High linearity, wide dynamic range and low distortion
•
Standby or Sleep mode in which the DAC is powered
down.
