AD5173BRMZ100 Products

The AD5172/AD5173BRMZ100 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/AD5173BRMZ100 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/ AD5173BRMZ100 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.

Feature

  • 2-channel, 256-position potentiometers
  • One-time programmable (OTP) set-and-forget resistance setting provides a low cost alternative to EEMEM
  • Unlimited adjustments prior to OTP activation
  • OTP overwrite allows dynamic adjustments with user-defined preset
  • End-to-end resistance: 2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ
  • Compact 10-lead MSOP: 3 mm × 4.9 mm
  • Fast settling time: tS = 5 μs typical in power-up
  • See Data Sheet for Additional Information
