  Application Note 62
  October 1994
  Data Acquisition Circuit Collection
  Kevin R. Hoskins
  INTRODUCTION
  This application note features 8-, 10-, and 12-bit data
  acquisition components in various circuit configurations.
  The circuits include battery monitoring, temperature sensing, isolated serial interfaces, and microprocessor and
  microcontroller serial and parallel interfaces. Also included are voltage reference circuits (Application Note 42
  contains more voltage reference circuits). Additional circuit information is located in the information
  references listed in the Circuit Index. Each information
  reference refers to either an application note (example:
  AN42 = Application Note 42), a data sheet (example:
  LTCВ®1292 DS = LTC1292 Data Sheet), or a design note
  (example: DN66 = Design Note 66).

  500ksps and 600ksps ADCs Match Needs of
  High Speed Applications – Design Note 88
  Kevin R. Hoskins Power Shutdown: 5mW Wakes Up in a Scant 300ns Single 5V or В±5V Supply Voltage Operation Low Power Dissipation: 150mW (Max), 75mW (Typ) Small 24-Pin SO or 24-Pin Narrow DIP Packages
  The LTC1278/LTC1279’s DC performance includes
  В±1LSB INL and DNL, no missing codes, and an internal
  voltage reference with a full-scale drift of only 25ppm/В°C.
  The AC performance includes 70dB (Min) SINAD,
  –78dB (Max) THD, and –82dB (Max) spurious-free
  dynamic range. These specifications were measured
  at fS = 500ksps (LTC1278) or fS = 600ksps (LTC1279),
  fIN = 100kHz, and are guaranteed over the operating
  temperature range. The plot of effective-number-of-bits
  (ENOB) shown in Figure 1 clearly indicates that the
  LTC1278/LTC1279 can accurately sample signals that
  contain spectral energy beyond the Nyquist frequency.
