The AD5172 / AD5173?are dual-channel, 256-position, one-time programmable (OTP) digital potentiometers that employ fuse link technology to achieve memory retention of resistance settings. The digital potentiometer, VR, and RDAC terms are used interchangeably. 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 reliability, and superior low temperature coefficient performance.TheAD5172 / 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 a fuse is blown. However, the OTP setting is restored during subsequent power-up conditions. This allows users to treat these digital potentiometers as volatile potentiometers with a programmable preset.APPLICATIONS Systems calibration Electronics level setting Mechanical trimmers replacement in new designs Permanent factory PCB setting Transducer adjustment of pressure, temperature, position, chemical, and optical sensors RF amplifier biasing Gain control and offset adjustment
