APPLICATIONS  
T he basic mode of adjustment is the increment and decrement  
command controlling the present setting of the Wiper position  
setting (RDAC) register. An internal scratch pad RDAC register  
can be moved UP or DOWN one step of the nominal terminal  
resistance between terminals A and B. T his linearly changes the  
wiper to B terminal resistance (RWB) by one position segment of  
the devices’ end-to-end resistance (RAB). For exponential/loga-  
rithmic changes in wiper setting, a left/right shift command  
adjusts levels in ±6 dB steps, which can be useful for audio and  
light alarm applications.

GENERAL D ESCRIP TIO N  
T he AD5232 device provides a nonvolatile, dual-channel,  
digitally controlled variable resistor (VR) with 256-position  
resolution. T hese devices perform the same electronic adjust-  
ment function as a potentiometer or variable resistor. T he  
AD5232s versatile programming via a microcontroller allows  
multiple modes of operation and adjustment.  
T he AD5232 is available in a thin T SSOP-16 package. All parts  
are guaranteed to operate over the extended industrial tempera-  
ture range of –40°C to +85°C. An evaluation board is available,  
Part Number: AD5232EVAL.  
In the direct program mode a predetermined setting of the RDAC  
register can be loaded directly from the microcontroller.  
Another key 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 estab-  
lish 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 register these values  
will be automatically transferred to the RDAC register to set the  
wiper position at system power ON. Such operation is enabled  
by the internal preset strobe and the preset can also be accessed  
externally.

All internal register contents can be read out of the serial data  
output (SDO). T his includes the RDAC1 and RDAC2 registers,  
the corresponding nonvolatile EEMEM1 and EEMEM2 regis-  
ters, and the 14 spare USER EEMEM registers available for  
constant storage.
