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.
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 ma-
trix 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.
