GENERAL DESCRIPTION
The AD5162 provides a compact 3 mm × 4.9 mm packaged
solution for dual 256-position adjustment applications. This
device performs the same electronic adjustment function as a
3-terminal mechanical potentiometer. Available in four different
end-to-end resistance values (2.5 k, 10 k, 50 k, 100 k),
this low temperature coefficient device is ideal for high accu-
racy and stability variable resistance adjustments. The wiper
settings are controllable through an SPI digital interface. The
resistance between the wiper and either endpoint of the fixed
resistor varies linearly with respect to the digital code
