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).
