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