  New 12-Bit Data Acquisition Systems Communicate with
  Microprocessors Over 4 Wires – Design Note 22
  As board space and semiconductor package pins become
  more valuable, serial data transfer methods between
  microprocessors (MPUs) and their peripherals become
  more and more attractive. Not only does this save lines
  in the transmission medium, but, because of the savings
  in the package pins, more function can be packed into
  both the MPU and the peripheral. Users are increasingly
  able to take advantage of these savings as more MPU
  manufacturers develop serial ports for their products (1-3).
  However, peripherals which are able to communicate with
  these MPUs must be available in order for users to take full
  advantage. Also, MPU serial formats are not standardized
  so not all peripherals can talk to all MPUs.
  The LTCВ®1290 Family
  A new family of 12-bit data acquisition circuits has been
  developed to communicate over just 4 wires to the recently
  developed MPU synchronous serial formats as well as
  to MPUs which do not have serial ports. These circuits
  feature software configurable analog circuitry including analog multiplexers, sample and holds, bipolar and
  unipolar conversion modes and the ability to shut power
  completely off. They also have serial ports which can be …
