Why are switching capacitor style DACs such as those implemented for VGA and TV signal generation left out? This article seems to concentrate entirely on DACs for the purpose of audio signal generation.
DACs are used in analogue signal processing circuits to replace potentiometers
I know what the writer is getting at, but these circuit elements are not really DACs, they are digitally controlled potentiometers ;-) In other words they do not create an analogue signal from a digital one, asa DAC does, but controls a purely analogue signal under digital control. Such devices are interesting and deserve an article, but they do not belong under DAC. Graham 05:50, 31 August 2005 (UTC)

I miss a history section..

The fact that practical DACs output a sequence of piecewise constant values or rectangular pulses
Rectangular pulse output was used to avoid the sinc roll-off of zero-order hold circuits. That is, rectangular pulse was used as an approximation of a dirac pulse. See for example this discussion:  So the use of the term "rectangular pulse" in the context of Nyquest-rate zero-order hold circuits is confusing: rectangular pulse DAC circuits are not Nyquest-rate zero-order hold circuits.220.127.116.11 (talk) 08:36, 30 November 2007 (UTC)
Dear fellow Wikipedians,
Is the "ring DAC"  significant enough to mention in this article? Or is it merely a minor variation of the "thermometer coded DAC" combined with a "oversampling DAC"? --18.104.22.168 (talk) 04:24, 2 July 2008 (UTC)
An edit war prompted me to review the Further reading and External links sections. I did not change Further reading. The ADI handbook appears be a valuable and accessible resource - lets not remove it. There were some things in External links that might be useful as references but the glssary link was the only thing that struck me as potentially valuable. Here are the links I removed. --Kvng (talk) 04:08, 16 August 2011 (UTC)

Odd paragraph in the introduction
Typical long distance telephone call
The text in the application section in no way describes a typical long distance telephone call. The voice public switched telephone network is not a packetized network. Phone calls over land lines have dedicated bandwidth from one end to the other. This section describes a voip system, which typical long distance calls are not. 22.214.171.124 (talk) 04:07, 3 December 2016 (UTC)
