GENERAL DESCRIPTION
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.
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.
