    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).

    William Rempfer Complete ADCs Provide Lowest Power and
    Highest Speed on Single or Dual Supplies
    The LTC1273/5/6 and LTC1282 provide complete
    A/D solutions at previously impossible speed/power
    levels. As shown in Table 1, the LTC1273/5/6 all have
    the same 300kHz maximum sampling rate and 75mW
    typical power dissipation. The LTC1273 digitizes 0V
    to 5V inputs from a single 5V rail. The LTC1275 and
    LTC1276 operate on В±5V rails and digitize В±2.5V and
    В±5V inputs, respectively.

    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.
