  12-Bit Rail-to-Rail Micropower DACs in an SO-8
  Design Note 96
  Hassan Malik and Jim Brubaker
  The LTC В®1451, LTC1452 and LTC1453 are complete,
  single supply, rail-to-rail voltage output 12-bit digitalto-analog (DAC) converters. They include an output
  buffer amplifier and a space saving SPI compatible
  three-wire serial interface. There is also a data output pin
  that allows daisy-chaining multiple DACs. These DACs
  use a proprietary architecture which guarantees a DNL
  (Differential Nonlinearity) error of less than 0.5LSB. The
  typical DNL error is about 0.2LSB as shown in FigureВ 1.
  There is a built-in power-on reset that resets the output
  to zero scale. The output amplifier can swing to within
  5mV of VCC when unloaded and can source or sink 5mA
  even at a 4.5V supply. These DACs come in an 8-pin
  PDIP and SO-8 package.
  5V and 3V Operation
  The LTC1451 has an on-board reference of 2.048V and
  a nominal output swing of 4.095V. It operates from a
  single 4.5V to 5.5V supply dissipating 2mW (ICC(TYP)
  = 400ОјA).
  The LTC1452 is a multiplying DAC with no on-board
  reference and a full-scale output of twice the reference …
