ANALOG DEVICES AD5170BRMZ2.5

AD5170 is a 256-position, two-time programmable, digital potentiometer that employs fuse link technology, giving users two opportunities to permanently program the resistance setting. The digital potentiometer, VR, and RDAC terms are used interchangeably. For users who do not need to program the digital potentiometer setting in memory more than once, the OTP feature is a cost-effective alternative to EEMEM. It performs the same electronic adjustment function as mechanical potentiometers or variable resistors with enhanced resolution, solid-state reliability, and superior low temperature coefficient performance. It is used in applications such as systems calibration, electronics level setting, mechanical trimmers replacement in new designs, permanent factory PCB settings, transducer adjustment of pressure, temperature, position, chemical, and optical sensors, RF amplifier biasing, gain control and offset adjustments.
