General Description
AD5173 General Description
The AD5172/AD5173 are dual channel, 256-position, one-time programmable (OTP) digital potentiometers1 that employ fuse link technology to achieve memory retention of resistance setting. 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. This device performs the same electronic adjustment function as mechanical potentiometers or variable resistors with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance.
The AD5172/AD5173 are programmed using a 2-wire, I2C compatible digital interface. Unlimited adjustments are allowed 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 the fuse has been blown. However, the OTP setting is restored during subsequent power- up conditions. This feature allows users to treat these digital potentiometers as volatile potentiometers with a programmable preset.
