In addition, for applications that program AD5273 at the factory,

Analog Devices offers device programming software²running in

Windows^®NT, 2000, and XP operating systems.This software

application effectively replaces any external I²C controllers, which

in turn enhances users’ systems time-to-market.

AD5273 is available in 1 k⍀, 10 k⍀, 50 k⍀, and 100 k⍀ in

compact SOT23 8-lead standard package and operates from

–40°C to +105°C.

Besides 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.

GENERAL DESCRIPTION

The AD5273 is a 64-position, One-Time-Programmable (OTP)

digital potentiometer⁴that employs fuse link technology to achieve

the permanent program setting.This device performs the same

electronic adjustment function as most mechanical trimmers and

variable resistors. It allows unlimited adjustments before perma-

nently setting the resistance values.The AD5273 is programmed

using a 2-wire, I²C compatible digital control. During the write

mode, a fuse blow command is executed after the ﬁnal value

is determined, therefore freezing the wiper position at a given

setting (analogous to placing epoxy on a mechanical trimmer).

When this permanent setting is achieved, the value will not change

regardless of the supply variations or environmental stresses under

normal operating 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

the read mode.

An AD5273 evaluation kit and software are available.The kit includes

the connector and cable that can be converted for further factory

programming applications.

For applications that require dynamic adjustment of resistance

settings with nonvolatile EEMEM, users should refer to AD523x

and AD525x families of nonvolatile memory digital potentiometers.

NOTES

¹One-Time-Programmable—Unlimited adjustments before permanent setting.

²ADI cannot guarantee the software to be 100% compatible in all systems due to

the wide variations in computer conﬁgurations.

³Applies to 1 k⍀ parts only.

⁴The terms digital potentiometer,VR, and RDAC are used interchangeably.
