GENERAL DESCRIPTION
The TDA1386T is a dual CMOS digital-to-analog converter
with up-sampling filter and noise shaper. The combination
of oversampling up to 4f
s
, noise shaping and continuous
calibration conversion ensures that only simple 1st order
analog post filtering is required.
The TDA1386T supports the I
2
S-bus data input mode with
word lengths of up to 20 bits and the LSB fixed serial data
input format 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.
