  DESIGN FEATURES Tiny 12-Bit ADC Delivers 2.2Msps
  Through 3-Wire Serial Interface
  by Joe Sousa
  Introduction
  Serial interfaces occupy little routing
  space, but usually limit the speed of
  an ADC. The LTC1402 has a full
  conversion speed of 2.2Msps and a
  very compact 3-wire interface for connecting to DSPs and microprocessors
  without glue logic. It comes in a 16-pin
  narrow SSOP package. This minuscule package (200mil Г— 230mil
  footprint) and compact serial interface are easy to fit close to sensors to
  best preserve analog signal integrity.
  Other serial 12-bit ADCs have
  sample rates limited to hundreds of
  kilosamples-per-second, which limits
  their utility in high speed data acquisition systems. This slow sample rate,
  combined with poor distortion characteristics, makes them unsuitable
  for tracking high frequency signals.
  The LTC1402 will capture, in less
  than 60ns, the fast steps from an
  external analog input multiplexer for
  high speed data acquisition and it will …
