... Preliminary Technical Data www.DataSheet4U.com OPERATION The AD5290 is a 256-position digitally controlled variable resistor device that can be controlled digitally through SPI interface. An internal power-on preset places the wiper at midscale during power-on, which simplifies the fault condition recovery at power-up. DETERMINING THE VARIABLE RESISTANCE ...

... DD SS SPI COMPATIBLE 3-WIRE SERIAL BUS The AD5290 contains a 3-wire SPI compatible digital interface (SDI and CLK). The 8-bit serial word must be loaded MSB first. The format of the word is shown in Table . The positive-edge sensitive CLK input requires clean transitions to avoid clocking incorrect data into the serial input register. ...
