Just a guess as to why DACs are more plentiful than ADCs: everyone wants to
here sound (PC, stereo, etc.) but a much smaller number of people need to
record/transmit sound. From a PC-centric point of view, almost every PC
sold has speakers, but a much smaller percentage have microphones.
For the cost, I've heard that it is much more difficult to
design/manufacture ADCs at the same quality level as DACs.

When I say an equivalent audio A to D Converter I mean with a minimum
resolution of 16 bits, a minimum sampling rate of 48KHz and the price at
about 0.5$ by channel...

Hello everybody,
I'm wonder why the audio A to D Converters are more expensive and fewer that
the audio D to A Converters.
Analog Devices produce only 3 audio ADCs and 13 audio DACs.
Texas Instruments manufacture 7 audio ADCs and 56 audio DACs.
For a low-cost and multi-channel application I found PCM1606 quite reliable
with 6 DAC channels for less that 3$ price.
Can anyone point me toward an equivalent A to D Converter?
Thanks,
Dan.
