The AD5259 provides a compact, nonvolatile LFCSP-10

(3 mm × 3 mm) or MSOP-10 (3 mm × 4.9 mm) packaged

solution for 256-position adjustment applications. These

devices perform the same electronic adjustment function

as mechanical potentiometers¹or variable resistors, but

with enhanced resolution and solid-state reliability.

Figure 3. Pinout

The wiper settings are controllable through an I²C-compatible

digital interface that is also used to read back the wiper register

and EEPROM content. Resistor tolerance is also stored within

EEPROM, providing an end-to-end tolerance accuracy of 0.1%.

¹The terms digital potentiometer, VR (variable resistor), and RDAC are used

interchangeably.

A separate V_LOGICpin delivers increased interface flexibility. For

users who need multiple parts on one bus, Address Bit AD0 and

Address Bit AD1 allow up to four devices on the same bus.
