  3V and 5V 12-Bit Rail-to-Rail Micropower DACs Combine
  Flexibility and Performance – Design Note 127
  Roger Zemke and Hassan Malik
  The LTCВ®1450 and LTC1450L are complete single supply
  rail-to-rail voltage output, 12-bit DACs in 24-pin SSOP
  and PDIP packages. They include an output buffer amplifier, a reference and a double-buffered parallel digital
  interface. These DACs use a proprietary architecture
  which guarantees a maximum DNL error of 0.5LSB. A
  built-in power-on reset ensures that the output of the
  DAC is initialized to zero scale. The LTC1450L draws 250ОјA from a 2.7V to 5.5V supply.
  It can be configured for a 0V to 2.5V or 0V to 1.22V
  output range. It has a 1.22V internal reference.
  Flexibility with Stand-Alone Performance
  The LTC1450/LTC1450L are complete stand-alone DACs
  requiring no external components. Reference output,
  reference input and gain setting pins provide the user
  with added flexibility. The rail-to-rail buffered output can source or sink 5mA
  while pulling to within 300mV of the positive supply
  voltage or ground. The output swings to within a few
  millivolts of either supply rail when unloaded and has
  an equivalent output resistance of 40О© when driving
  a load to the rails. Figure 1 shows how these DACs may typically be used.
  REF HI is tied to REF OUT and REF LO and X1/X2 are …
