SCL
OPERATION
The LTC3207/LTC3207-1 are receive-only (slave) devices.
There are two I
address is 00110110 and the LTC3207-1 I
00110100. The I
the LTC3207 and the LTC3207-1.
Bus Speed
The I
to 400kHz. It has built-in timing delays to ensure correct
operation when addressed from an I
device. It also contains input fi lters designed to suppress
glitches should the bus become corrupt.
SDA
Write Word Protocol Used by the LTC3207/LTC3207-1
S = Start Condition, Wr = Write Bit = 0, A = Acknowledge,
P = Stop Condition
*The sub-address uses only the fi rst four bits, D0, D1, D2 and D3
**Stop can be delayed until all of the data registers have been written
