GENERAL DESCRIPTION
The AD5161 provides a compact 3 mm × 4.9 mm packaged
solution for 256-position adjustment applications. These
devices perform the same electronic adjustment function as
mechanical potentiometers or variable resistors, with enhanced
resolution, solid-state reliability, and superior low temperature
coefficient performance.
The wiper settings are controllable through a pin selectable SPI
or I2C compatible digital interface, which can also be used to
read back the wiper register content. When the SPI mode is
used, the device can be daisy-chained (SDO to SDI), allowing
several parts to share the same control lines. In the I2C mode,
address pin AD0 can be used to place up to two devices on the
same bus. In this same mode, command bits are available to
reset the wiper position to midscale or to shut down the device
into a state of zero power consumption.
Operating from a 2.7 V to 5.5 V power supply and consuming
less than 5 A allows for usage in portable battery-operated
applications.
