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 k, 10 k, 50 k, and 100 k),
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
have three hard-coded slave address options available to allow
for a full list of slave address locations).
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 A (3.3 V) allows the AD5247 to be used in portable
battery-operated applications.
