256-Position One-Time Programmable

Dual-Channel I²C Digital Potentiometer

Preliminary Technical Data

AD5172/AD5173

The AD5172/73 are programmed using a 2-wire I²C compatible

digital control. They allow unlimited adjustments before

permanently setting the resistance value. During the OTP

FEATURES

2-Channel, 256-position

OTP(One-Time Programmable) Set-and-Forget Resistance

Setting — low cost alternative over EEMEM

Unlimited adjustments prior to OTP activation

OTP overwriting function allows temporary adjustments¹

End-to-end resistance 2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ

Compact MSOP-10 (3 mm × 4.9 mm) Package

Low tempco 5 ppm/^oC in potentiometer mode

Low tempco 35 ppm/°C in rheostat mode

activation, a permanent fuse blown command is sent after the

final value is determined; therefore freezing the wiper position

at a given setting (analogous to placing epoxy on a mechanical

trimmer). Unlike other OTP digital potentiometers in the same

family, AD5172/73 have unique temporary OTP overwriting

feature that new adjustments if desired but the OTP setting is

restored during subsequent power up conditions. To verify the

success of permanent programming, Analog Devices patterned

the OTP validation such that the fuse status can be discerned

from two validation bits in read mode.

Fast Settling Time: t_S= 5µs Typ in Power-Up

Full read/write of wiper register

Power-on preset to midscale¹

For applications that program AD5172/73 in the factories,

Analog Devices offers a device programming software, which

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 users’ development time.

Extra package address decode pins AD0 and AD1(AD5173)

Computer Software Replaces µC in Factory Programming

Applications

6 V one-time programming voltage

Single supply 2.7 V to 5.5 V

Low power, I_DD= 5 µA

Wide operating temperature –40°C to +125°C

An AD5172/73 evaluation kit is available, which include the

software, connector, and cable that can be converted for the

factory programming applications.

APPLICATIONS

The AD5172/73 are available in a MSOP-10 package. All parts

are guaranteed to operate over the automotive temperature

range of −40°C to +125°C. Besides their unique OTP features,

the AD5172/73 lend themselves well to other general-purpose

digital potentiometer applications due to their programmable

preset, superior temperature stability, and small form factor.

GENERAL OVERVIEW

FUSE

The AD5172/73 are dual channel 256-position, one-time

programmable (OTP) digital potentiometers², which employ

fuse link technology to achieve the memory retention of

resistance setting function. OTP is a cost-effective alternative

over the EEMEM approach for users who do not need to

program the digital potentiometer setting in memory for more

than once. These devices perform the same electronic

adjustment functions like most mechanical trimmers and

variable resistors do but offer enhanced resolution, solid-state

reliability, and superior low temperature coefficient

performance.
