Synchronizing Multiple LTC2487s with a Global
Address Call
In applications where several LTC2487s (or other I2C
delta-sigma ADCs from Linear Technology Corporation)
are used on the same I2C bus, all converters can be syn-
chronized through the use of a global address call. Prior
to issuing the global address call, all converters must have
completed a conversion cycle. The master then issues a
Start, followed by the global address 1110111, and a write
request. All converters will be selected and acknowledge
the request. The master then sends a write byte (optional)
followed by the Stop command. This will update the chan-
nel selection (optional) converter conguration (optional)
and simultaneously initiate a start of conversion for all
delta-sigma ADCs on the bus (see Figure 10). In order
to synchronize multiple converters without changing
the channel or conguration, a Stop may be issued after
acknowledgement of the global write command. Global
read commands are not allowed and the converters will
NAK a global read request.
