2C Protocol Information
The I
2C address for the LM4947 is determined using the
ID_ENB pin. The LM4947’s two possible I
2C chip addresses
are of the form 111110X
10
(binary), where X
1
=0,if
ID_ADDR is logic LOW; and X
1 = 1, if ID_ENB is logic HIGH.
If the I
2C interface is used to address a number of chips in a
system, the LM4947’s chip address can be changed to avoid
any possible address conflicts.
