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.
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.
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 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.
