General Description
The DS3902 features a dual, nonvolatile (NV), low tem-
perature-coefficient, variable digital resistor with 256
user-selectable positions. The DS3902 can operate
over a wide supply range of 2.4V to 5.5V, and commu-
nication with the device is achieved through an I
2
C-
compatible serial interface. Internal address settings
allow the DS3902 slave address to be programmed to
one of 128 possible addresses. The low cost and the
small size of the DS3902 make it an ideal replacement
for conventional mechanical-trimming resistors.
Applications
Optical Transceivers
Optical Transponders
Instrumentation and Industrial Controls
