GENERAL DESCRIPTION
The TDA1306T is a dual CMOS digital-to-analog
converter with up-sampling filter and noise shaper.
The combination of oversampling up to 4fs, noise shaping
and continuous calibration conversion ensures that only
simple 1st-order analog post-filtering is required.
The TDA1306T supports the I2S-bus data input mode
(fsys = 256fs) with word lengths of up to 20 bits and the
LSB fixed serial data input format (fsys = 384fs) with word
lengths of 16, 18 or 20 bits. Two cascaded IIR filters
increase the sampling rate 4 times.
The DACs are of the continuous calibration type and
incorporate a special data coding. This ensures a high
signal-to-noise ratio, wide dynamic range and immunity to
process variation and component ageing.
Two on-board operational amplifiers convert the
digital-to-analog current to an output voltage.
