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,

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 …
