  DESIGN FEATURES An SMBus-Controlled 10-Bit, Current
  Output, 50ВµA Full-Scale DAC by Ricky Chow 6 precision full-scale current is trimmed
  to В±1.5% at room temperature and
  В±2.5% over the commercial temperature range.
  There are two ways to shut down
  the LTC1427 (see Figure 2). A logic
  low at the SHDN pin or a logic high at
  bit 7 of the command byte sent
  through the SMBus interface will put
  the LTC1427 into shutdown mode. In
  shutdown mode, the digital data is
  retained internally and the supply
  current drops to only 12ВµA typically. SMBus WRITE BYTE PROTOCOL, WITH SMBus ADDRESS = 0101111B,
  COMMAND BYTE = 0XXXXX11B AND DATA BYTE = 11111111B, AD1 = 0, AD0 =1 SDA COMMAND BYTE 0 1 0 1 1 1 1 1 2 3 4 5 6 7 8 X X X X X DATA BYTE
  1 1 1 1 1 1 1 1 1 1 ACK SMBus ADDRESS ACK The LTC1427-50 communicates with
  external circuitry using the standard
  2-wire I2C or SMBus interface. The
  operating sequence (Figure 1) shows
  the signals on the SMBus. The two
  bus lines, SDA and SCL, must be high
  when the bus is not in use. External
  pull-up resistors are required on these
  lines. The LTC1427-50 is a receiveonly (slave) device; the system master …
