The FSDAC is a semi-digital reconstruction filter that
converts the 1-bit data stream of the noise shaper to an
analog output voltage. The filter coefficients are
implemented as current sources and are summed at virtual
ground of the output operational amplifier. In this way very
high signal-to-noise performance and low clock jitter
sensitivity is achieved. A post filter is not needed due to the
inherent filter function of the DAC. On-board amplifiers
convert the FSDAC output current to an output voltage
signal capable of driving a line output.

The UDA1341TS supports the following data formats:
• I
• MSB-justified serial format with word length up to 20 bits
• LSB-justified serial format with word length of
• MSB data output with LSB 16, 18 or 20 bits input.
Left and right data-channel words are time multiplexed.
The formats are illustrated in Fig.4.
The UDA1341TS allows for double speed data monitoring
purposes. In this case the sound features bass boost,
treble and de-emphasis cannot be used. However, volume
control and soft-mute can still be controlled. The double
speed monitoring option can be set via the L3-interface.
The bit clock frequency must be 64 times word select
frequency or less, so f
