10 / 12 page –10– REV. 0 ADG728/ADG729 WRITE OPERATION When writing to the ADG728/ADG729, the user must begin with an address byte and R/ W bit, after which the switch will acknowledge that it is prepared to receive data by pulling SDA low. This address byte is followed by the 8-bit word. The write operations for each matrix switch are shown in the figures below.

ADG729 Write Sequence READ OPERATION When reading data back from the ADG728/ADG729, the user must begin with an address byte and R/ W bit, after which the matrix switch will acknowledge that it is prepared to transmit data by pulling SDA low. The readback operation is a single byte that consists of the eight data bits in the input register. The read operations for each part are shown in Figures 18 and 19.
