GENERAL DESCRIPTION
The AD5263 is the industry’s first quad-channel, 256-position, digital potentiometer 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.
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-tochannel matching tolerance.
Another key feature of this part is  the ability to operate from +4.5 V to +15V, or at ±5V.
