Product specification
Quadruple filter DAC
TDA1314T
FEATURES
High dynamic range to enable digital DSP (Digital Signal
Processor) volume control
18 bits data input format for each of the four channels
Four times bit-serial oversampling filter
1st-order 4f
as
(audio sampling frequency) noise shaper
Four very low noise DACs
Only 1st-order analog post filtering required
Smooth power-on of the DAC output currents
Because of the automatic digital PLL divider range
setting the master clock is selectable in a wide 4f
as
integer range
Insensitive to jitter on the I
2
S-bus signals with respect to
the DAC total harmonic distortion deterioration.
APPLICATIONS
Stand-alone quadruple low noise DAC
Car radio DAC in conjunction with DSP.
GENERAL DESCRIPTION
The TDA1314T is a quadruple very low noise high
dynamic range DAC which is intended for use in motor
cars and is controlled by the car radio DSP. Each channel
incorporates an 8th-order IIR up-sampling filter from 1ASF
to 4ASF followed by a 1st-order noise shaper and DAC.
The DAC currents are converted to audio voltage signals
using operational amplifiers (one per channel).
