Digital Potentiometer ICs IC Dual OTP 8Bit I2C
IC DGTL POT 50KOHM 256TAP 10MSOP
IC POT DUAL 50K 256POS 10-MSOP
256-POSITION, DUAL I2C DIGI-POT
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 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 with enhanced resolution, solid-state reliabil-ity, 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 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. 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 Automotive electronics adjustment Gain control and offset adjustment 1 The terms digital potentiometer, VR, and RDAC are used interchangeably.
