ADCs FOR DSP APPLICATIONS
Walt Kester, James Bryant
The trend in ADCs and DACs is toward higher speeds and higher resolutions at
reduced power levels and supply voltages. Modern data converters generally operate
on ±5V (dual supply), +5V or +3V (single supply). In fact, the number of +3V devices
is rapidly increasing because of many
