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 В±5V rails and digitize В±2.5V and
В±5V inputs, respectively.

500ksps and 600ksps ADCs Match Needs of
High Speed Applications вЂ“ 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/LTC1279вЂ™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,
вЂ“78dB (Max) THD, and вЂ“82dB (Max) spurious-free
dynamic range. These speciп¬Ѓcations 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.
