GENERAL DESCRIPTION
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 potentiometers
1
or variable resistors, but
with enhanced resolution and solid-state reliability.
The wiper settings are controllable through an I
2
C-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%.
A separate V
LOGIC
pin 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.
