Automotive electronics adjustment  
Gain control and offset adjustment  
have three hard-coded slave address options available to allow

for a full list of slave address locations).  
GENERAL DESCRIPTION  
The AD5247 provides a compact, 2 mm × 2.1 mm, packaged  
solution for 128-position adjustment applications. This device  
performs the same electronic adjustment function as a mechanical  
potentiometer or a variable resistor. Available in four different  
end-to-end resistance values (5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ),  
these low temperature coefficient devices are ideal for high  
accuracy and stability variable resistance adjustments.  
The wiper settings are controllable through the I2C-compatible  
digital interface, which can also be used to read back the present  
wiper register control word. The 10 kΩ and 100 kΩ options each  
The resistance between the wiper and either end point of  
the fixed resistor varies linearly with respect to the digital  
code transferred into the RDAC latch. Note the terms digital  
potentiometer, VR (variable resistor), and RDAC are used  
interchangeably in this document.  
Operating from a 2.7 V to 5.5 V power supply and consuming  
0.9 µA (3.3 V) allows the AD5247 to be used in portable  
battery-operated applications.
