AD5162
SPI INTERFACE
SPI-COMPATIBLE, 3-WIRE SERIAL BUS
The AD5162 contains a 3-wire, SPI-compatible digital interface
(SDI, CS , and CLK). The 9-bit serial word must be loaded MSB
first. The format of the word is shown in Table 8.
The positive-edge sensitive CLK input requires clean transitions
to avoid clocking incorrect data into the serial input register.
Standard logic families work well. If mechanical switches are
used for product evaluation, they should be debounced by a
flip-flop or another suitable means. When CS is low, the clock
loads data into the serial register on each positive clock edge
(see Figure 42).
The data setup and data hold times in Table 3 determine the
valid timing requirements. The AD5162 uses a 9-bit serial input
data register word that is transferred to the internal RDAC
register when the CS line returns to logic high. Extra MSB bits
are ignored.
