Alan,
The great majority of current production Delta Sigma DACs are not single bit, but rather, utilize relatively low resolution multibit PCM resistor-ladder quantizers. Examples include, Burr-Brown's PCM179x series, Analog Devices' AD1853 and AD1955, Cirrus' CS4398, AKM's AK439x series, Wolfson's WM874x series, and ESS' Sabre series. True single bit DACs featuring noise-shaping, such as utilized for DSD, are the less common devices.
Multibit sigma-delta DACs are a sort of hybrid, combining low resolution, but still PCM, resistor-ladder quantizers with noise-shaping.
