GENERAL CALL READ ADDRESS
BITS
This command is used to read the I2C address bits of
the device. If the second byte is “00001100” (0Ch), the
device will output its address bits stored in EEPROM
and register. This command uses the LDAC pin to
select the device of interest to read on the I2C bus. The
LDAC pin needs a logic transition from “High” to “Low”
during the negative pulse of the 8th clock of the second
byte, and stays “Low” until the end of the 3rd byte. The
maximum clock rate for this command is 400 kHz.

2:
LDAC pin events at the 2nd and 3rd bytes.
a.
Keep LDAC pin “High” until the end of the positive pulse of the 8th clock of the 2nd byte.
b.
LDAC pin makes a transition from “High” to “Low” during the negative pulse of the 8th clock of the 2nd
byte (just before the rising edge of the 9th clock) and stays “Low” until the rising edge of clock 9 of the
3rd byte.
c.
The MCP4728 device does not acknowledge the 3rd byte if the conditions (a) and (b) are not met.
3: LDAC pin resumes its normal function after “Stop” bit.
