with a single 16-bit control word. The control word con-
sists of two don’t care MSBs, the chip address bits, out-
put address bits, an output enable/disable bit, an
output gain-set bit, and input address bits (Tables 2
through 6, and Figure 2).
In mode 0, data at DIN passes directly to DOUT
through the data routing gate (Figure 3). In this configu-
ration, the 16-bit control word is simultaneously sent to
all chips in an array of up to 16 addresses.
Drive MODE to logic-high to select mode 1. A single
96-bit control word consisting of sixteen 6-bit control
words programs all outputs. The 96-bit control word’s

FUNCTION
Switch with Programmable Gain
first 6-bit control word (MSBs) programs output 15, and
the last 6-bit control word (LSBs) programs output 0
(Table 7 and Figures 4 and 5). Data clocked into the
96-bit Complete Matrix Mode register is latched on the
falling edge of UPDATE, and the outputs are immedi-
ately updated.
The Complete Matrix Mode (Mode = 1) is convenient to
use to program the matrix at power-up. In a large
matrix consisting of many MAX9675 devices, all the
devices can be programmed by sending a single bit
stream equal to n x 96 bits, where n is the number of
MAX9675 devices on the bus. The first 96-bit data word
programs the last MAX9675 in line (see the Matrix
Programming section) .
