AD5173BRMZ10

AD5173BRMZ10 is a 256-position, one-time programmable, dual-channel, I²C digital potentiometer. It employs 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. This device performs the same electronic adjustment function as mechanical potentiometers or variable resistors but with enhanced resolution, solid-state reliability, and superior low-temperature coefficient performance. It is programmed using a 2-wire, I²C-compatible digital interface. It is used in applications such as 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.
