General Description
AD5171 General Description
The AD5171 is a 64-position, one-time programmable (OTP) digital potentiometer2 , which employs fuse link technology to achieve the memory retention of resistance setting function. OTP is a cost-effective alternative over the EEMEM approach for users who do not need to reprogram new memory setting in the digital potentiometer. This device performs the same electronic adjustment function like most mechanical trimmers and variable resistors do. The AD5171 is programmed using a 2-wire I2C compatible digital control. It allows unlimited adjustments before permanently setting the resistance value.
For applications that program AD5171 in the factories, Analog Devices offers a device programming software, which operates across Windows® 95 to XP® platforms including Windows NT®. This software application effectively replaces the need for external I2C controllers or host processors and therefore
significantly reduces users' development time. An AD5171 evaluation kit is available, which includes the software, connector, and cable that can be converted for the factory programming applications.
