GENERAL DESCRIPTION

The AD5235 provides a dual channel, digitally controlled variable

resistor (VR) with resolutions of 1024 positions. These devices

perform the same electronic adjustment function as a potentiometer or

variable resistor. The AD5235’s versatile programming via a Micro

Controller allows multiple modes of operation and adjustment.

In the direct program mode a predetermined setting of the RDAC

mode of operation allows the RDAC register to be refreshed with the

setting previously stored in the EEMEM register. When changes are

made to the RDAC register to establish a new wiper position, the

value of the setting can be saved into the EEMEM by executing an

EEMEM save operation. Once the settings are saved in the EEMEM

is enabled by the internal preset strobe and the preset can also be

accessed externally.

An internal scratch pad RDAC register can be programmed by the

micro controller to set the resistance between terminals W-and-B.

Once the target value is achieved, the RDAC content register can be

placed in the non-volatile memory for automatic recall during Power

Up.

The AD5235 is available in the thin TSSOP-16 package. All parts are

guaranteed to operate over the extended industrial temperature range

of -40°C to +85°C.
