Monolithic/Hybrid Analog To Digital (A/D) Converter Posted: 06 Jul 2011 03:06 AM PDT The basic ANALOG TO DIGITAL (A/D) CONVERTER CIRCUIT has already been explained in an earlier post. Apart from it, there are also many types of monolithic analog to digital converters, such as the integrating A/D, integrating A/D with three-stage outputs, and the tracking A/D with latched outputs. In addition to this, the outputs of A/D are coded in straight binary, binary-coded decimal (BCD), complementary binary (l’s or 2′s), sign-magnitude binary, and so on. The figure below illustrates an 8-bit monolithic CMOS analog to digital converter with three-state output. The converter is made compatible with a microprocessor and it also exhibits high stability over a full temperature range. It has all the needed active elements, and has latched parallel binary outputs with strobed or free-running conversion. It has an infinite input range since any positive voltage can be applied through a scaling register Rin. The circuit diagram of a Teledyne 8703 8-bit Monolithic CMOS analog to digital converter is given below. It is a 24-pin DIP package. (Courtesy: Teledyne Semi-conductor) Teledyne 8703 8-Bit CMOS Analog-to-Digital Converter As in the case of monolithics, there are many hybrid A/D converters, such as the successive-approximation A/D with input buffer amplifier, the low-power CMOS... |
