GENERAL DESCRIPTION  
Wiper position programming presets to midscale upon power-  
on. Once powered, the VR wiper position is programmed by  
either the 3-wire SPI or 2-wire I2C-compatible interface. In the  
I2C mode, additional programmable logic outputs enable users  
to drive digital loads, logic gates, and analog switches in their  
systems.  
The AD5263 is the industry’s first quad-channel, 256-position,  
digital potentiometer1 with a selectable digital interface. This  
device performs the same electronic adjustment function as  
mechanical potentiometers or variable resistors, with enhanced  
resolution, solid-state reliability, and superior low temperature  
coefficient performance.  
The AD5263 is available in a narrow body, 24-lead TSSOP.  
All parts are guaranteed to operate over the automotive  
temperature range of –40°C to +125°C.  
Each channel of the AD5263 offers a completely programmable  
value of resistance between the A terminal and the wiper or  
between the B terminal and the wiper. The fixed A-to-B  
terminal resistance of 20 kΩ, 50 kΩ, or 200 kΩ has a nominal  
temperature coefficient of 30 ppm/°C and a 1% channel-to-  
channel matching tolerance. Another key feature of this part is  
the ability to operate from +4.5 V to +15 V, or at 5 V.  
For single- or dual-channel applications, refer to the  
AD5260/AD5280 or AD5262/AD5282 data sheets.  
1 The terms digital potentiometer, VR, and RDAC are used interchangeably.
