MULTI-STEP PARALLEL ANALOG-DIGITAL CONVERTER

摘要

A multi-step A/D converter of the successive approximation type utilizes a single three-position switchable current-output DAC in combination with a voltage divider, a plurality of comparators, a decoder, a successive approximation register and a control logic module to provide a high speed, high resolution A/D converter requiring fewer parts than the prior art A/D converters of this general type.
