The successive approximation ADC has been the mainstay of data acquisition systems for many years. Recent design improvements have extended the sampling frequency of these ADCs into the megahertz region with 18-bit resolution. The Analog Devices PulSAR® family of SAR ADCs uses internal switched capacitor techniques along with auto calibration and offers 18-bits at 2 MSPS (AD7641) on CMOS processes without the need for expensive thin-film laser trimming. At the 16-bit level, the AD7625 (6 MSPS) and AD7626 (10 MSPS) also represent breakthrough technology
