GENERAL OVERVIEW
The AD5259 provides a compact nonvolatile 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 and solid-state reliability.
The wiper settings are controllable through an I2C compatible
digital interface, which can also be used to read back the wiper
register and EEMEM content. Resistor tolerance is also stored
within EEMEM and can be used to provide an end-to-end
tolerance accuracy of 0.1%. In order to provide added security,
command bits are available to place the part into a write protect
mode in which data can not be written to the EEMEM register.
In addition, a separate VLOGIC pin provides the user with
increased interface flexibility. For users who need multiple
parts on one bus, address bits AD0 and AD1 allow up to nine
devices on the same bus.
