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.

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... Dan.

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.
