GENERAL DESCRIPTION
The AD5273 is a 64-position, one-time programmable (OTP)
digital potentiometer4 that employs fuse link technology to
achieve permanent program setting. This device performs the
same electronic adjustment function as most mechanical
trimmers and variable resistors. It allows unlimited adjustments
before permanently setting the resistance values. The AD5273 is
programmed using a 2-wire, I2C-compatible digital control.
During write mode, a fuse blow command is executed after the
final value is determined, thereby freezing the wiper position at
a given setting (analogous to placing epoxy on a mechanical
trimmer). When the permanent setting is achieved, the value
does not change, regardless of the supply variations or environ-
mental stresses under normal operating conditions. To verify
the success of permanent programming, Analog Devices, Inc.,
patterned the OTP validation such that the fuse status can be
discerned from two validation bits in the read mode.

In addition, for applications that program the AD5273 at the
factory, Analog Devices offers device programming software2
running on Windows NT, Windows 2000, and Windows XP
operating systems. This software application effectively replaces
any external I2C controllers, which in turn enhances the user
system’s time-to-market.
The AD5273 is available in 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ
resistances and in a compact 8-lead SOT-23 standard package.
It operates from 40°C to +105°C.
Along with its unique OTP feature, the AD5273 lends itself
well to general digital potentiometer applications due to its
effective resolution, array resistance options, small footprint,
and low cost.
An AD5273 evaluation kit and software are available. The kit
includes the connector and cable that can be converted for
factory programming applications.
For applications that require dynamic adjustment of resistance
settings with nonvolatile EEMEM, users should refer to the
AD523x and AD525x families of nonvolatile memory digital
potentiometers.
1 OTP allows unlimited adjustments before permanent setting.
2 Analog Devices cannot guarantee the software to be 100% compatible to all
systems due to the wide variation in computer configurations.
3 Applies to 1 kΩ parts only.
4 The terms digital potentiometer, VR, and RDAC are used interchangeably.
