  16mW, Serial/Parallel 14-Bit ADC Samples at 200ksps
  Design Note 180
  Chi Fai Yeung and Kevin R. Hoskins
  Introduction
  The new LTC В®1418 14-bit ADC samples at 200ksps,
  consuming only 16mW from a single 5V supply. Its pin
  configurable serial or parallel interface is designed to
  be versatile, easy to use and adaptable, requiring little
  or no support circuitry in a wide variety of applications.
  Some of the key features of this new device include: 200ksps Throughput Low Power: 16mW Parallel and Serial Data Output Modes 1.25LSB INL Max and 1LSB DNL Max Two Input Ranges: 0V to 4.096V with 5V Supply;
  В±2.048V with В±5V Supply NAP and SLEEP Power Shutdown Modes Small Package: 28-Pin SSOP
  High Performance Without High Power
  As shown in Figure 1, the LTC1418 includes a high
  performance differential sample-and-hold circuit, an
  ultra efficient successive approximation ADC, an on-chip
  reference, and a digital interface that allows easy serial
  or parallel interface to a microprocessor, FIFO or DSP. The LTC1418’s factory calibrated 14-bit performance is
  achieved without requiring any autocalibration cycles.
  The result is a 1LSB (max) differential linearity error,
  no missing codes and 1.25LSB (max) integral linearity
  error guaranteed over temperature.
  For AC applications the dynamic performance of the
  LTC1418 is exceptional. The low distortion, differential …
