GENERAL DESCRIPTION
The AD5171 is a 64-position, one-time programmable (OTP)
digital potentiometer2 that uses fuse link technology to achieve
the memory retention of the resistance setting function. OTP is
a cost-effective alternative over the EEMEM approach for users
who do not need to reprogram new memory settings in the
digital potentiometer. This device performs the same electronic
adjustment function as most mechanical trimmers and variable
resistors. The AD5171 is programmed using a 2-wire, I2C-
compatible digital control. It allows unlimited adjustments
before permanently setting the resistance value. During the
OTP activation, a permanent fuse blown command is sent after the
final value is determined, freezing the wiper position at a given
setting (analogous to placing epoxy on a mechanical trimmer).

Figure 2. Pin Configuration
When this permanent setting is achieved, the value does not
change regardless of supply variations or environmental 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 read mode.
For applications that program the AD5171 in factories, Analog
Devices offers device programming software that operates
across Windows 95 to XP platforms, including Windows NT.
This software application effectively replaces the need for external
I2C controllers or host processors and, therefore, significantly
reduces the development time of the users.
An AD5171 evaluation kit includes the software, connector, and
cable that can be converted for factory programming applications.
The AD5171 is available in a compact 8-lead SOT-23 package.
All parts are guaranteed to operate over the automotive temper-
ature range of 40°C to +125°C. Besides its unique OTP feature,
the AD5171 lends itself well to other general-purpose digital
potentiometer applications due to its temperature performance,
small form factor, and low cost.
1 Applies to 5 kΩ parts only.
2 The terms digital potentiometer and RDAC are used interchangeably.
