GENERAL DESCRIPTION

The AD5172/AD5173 are dual-channel, 256-position, one-time

programmable (OTP) digital potentiometers¹that employ fuse

link technology to achieve memory retention of resistance

settings. OTP is a cost-effective alternative to EEMEM for users

who do not need to program the digital potentiometer setting

in memory more than once. These devices perform the same

electronic adjustment function as mechanical potentiometers or

variable resistors but with enhanced resolution, solid-state reliabil-

ity, and superior low temperature coefficient performance.

before permanently setting the resistance value. During OTP

activation, a permanent blow fuse command freezes the wiper

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

Unlike traditional OTP digital potentiometers, the AD5172/

AD5173 have a unique temporary OTP overwrite feature that

allows for new adjustments even after a fuse is blown. However,

the OTP setting is restored during subsequent power-up condi-

tions. This allows users to treat these digital potentiometers as

volatile potentiometers with a programmable preset.

The AD5172/AD5173 are programmed using a 2-wire, I²C®-

compatible digital interface. Unlimited adjustments are allowed

¹The terms digital potentiometer, VR, and RDAC are used interchangeably.
