  Upgrade Your Microcontroller ADC to True 12-Bit Performance
  Design Note DN463
  by Guy Hoover
  Introduction
  Many 8-bit and 16-bit microcontrollers feature 10-bit
  internal ADCs. A few include 12-bit ADCs, but these often
  have poor or nonexistent AC specifications, and certainly
  lack the performance to meet the needs of an increasing
  number of applications. The LTC В®2366 and its slower
  speed versions offer a high performance alternative, as
  shown in the AC specifications in Table 1. Compare these
  guaranteed specifications with the ADC built into your
  current microcontroller.
  This family’s DC specifications are equally impressive. INL
  and DNL are guaranteed to be less than В±1LSB. Operating
  from a single 2.5V, 3V or 3.3V supply, the current draw
  on these parts is a maximum of 4mA during a conversion. This can be reduced to less than 1ОјA by placing
  the part into SLEEP mode during periods of inactivity,
  which greatly reduces the average supply current at lower
  sample rates.

  and OVDD pins. The adjustable VREF pin allows the input …
