    New 5V and 3V, 12-Bit ADCs Sample at 300kHz on 75mW
    and 140kHz on 12mW -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 ±5V rails and digitize ±2.5V and
    ±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 ±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
    ±1LSB INL and DNL, no missing codes, and an internal
    voltage reference with a full-scale drift of only 25ppm/°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.
