AD5170BRMZ10 Datasheet PDF - ADI

●The AD5170BRMZ10 is a two-time programmable Digital Potentiometer employs fuse link technology, giving users two opportunities to permanently program the resistance setting. For users who do not need to program the digital potentiometer setting in memory more than once, the OTP feature is an alternative to EEMEM. The AD5170 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 AD5170 is programmed using a 2-wire, I²C®-compatible digital interface. Unlimited adjustments are allowed before permanently setting the resistance value and there are two opportunities for permanent programming. During OTP activation, a permanent blow fuse command freezes the wiper position (analogous to placing epoxy on a mechanical trimmer).

● Two-time programmable set-and-forget resistance setting allows second-chance permanent programming

● Unlimited adjustments prior to one-time programming (OTP) activation

● OTP overwrite allows dynamic adjustments with user-defined preset

● Full read/write of wiper register

● power-ON preset to midscale
