Operation Sequence
The LTC2489 acts as a transmitter or receiver, as shown
in Figure 4. The device may be programmed to select
an input channel, differential or single-ended mode, and
channel polarity.

Continuous Read
In applications where the input channel does not need to
change for each cycle, the conversion can be continuously
performed and read without a write cycle (see Figure 5).
The input channel remains unchanged from the last value
written into the device. If the device has not been writ-
ten to since power up, the channel selection is set to the
default value of CH0 = IN+, CH1 = IN–. At the end of a read
operation, a new conversion automatically begins. At the
conclusion of the conversion cycle, the next result may
be read using the method described above. If the conver-
sion cycle is not concluded and a valid address selects
the device, the LTC2489 generates a NAK signal indicating
the conversion cycle is in progress.
Continuous Read/Write
Once the conversion cycle is concluded, the LTC2489 can
be written to and then read from using the Repeated Start
(Sr) command.
