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.
