  DESIGN FEATURES Introduction Product Family Overview Linear Technology’s Delta-Sigma analog-to-digital converter product family
  simplifies a variety of applications.
  The products’ ease-of-use and high
  accuracy without the need for calibration, external clocks or complex
  interfaces enables designers to rethink
  their system architectures.
  Although 24 bits may seem excessive to some, many designers find
  significant advantages with these
  higher resolution converters. One
  such advantage is the elimination of
  front-end amplification. This enables
  direct digitization of many sensors
  while removing problems associated
  with front-end offset and gain errors
  as well as simplifying tare adjustments. One misconception commonly
  solved by designers using the
  LTC2400 family is the relationship
  between speed and resolution. Many
  designers have found that higher
  speed ADCs with averaging do not
  meet the one-shot performance of the
  LTC2400 family. The absolute accuracy of the LTC2400 family is
  demonstrated using a bridge sensor …

  DESIGN INFORMATION A New, Fully Differential, No Latency
  Delta-Sigma ADC Family by Michael K. Mayes
  Introduction
  In recent years, Linear Technology
  has introduced a family of high resolution delta-sigma analog-to-digital
  converters. Originating from the
  LTC2400, this product family features high accuracy (10ppm total
  error), ease of use (8-pins, on-chip
  oscillator, no latency) and low drift
  (user-transparent offset/full-scale
  calibration). This product family
  includes single-ended one-, two-, fourand eight-channel input devices with
  user-selectable 50Hz or 60Hz linefrequency rejection.
  A new family of differential-input
  delta-sigma analog-to-digital converters is introduced here. These
  converters offer features similar to
  those of the previous family, with the
  addition of differential input and differential reference. All devices offer
  compatible timing and interface with
  the original LTC2400, as well as transparent calibration, no latency, on-chip
  oscillator and wide supply (2.7V–
  5.5V), input and reference ranges.
  The first part, the LTC2410, features 0.1ppm offset error, 2ppm INL, …
