AD5171 APPLICATIONS For applications that program the AD5171 in factories, Analog Devices offers device programming software that operates across Windows(R) 95 to XP(R) platforms including Windows NT(R). 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 factory programming applications. The AD5171 is available in a compact SOT-23-8 package. All parts are guaranteed to operate over the automotive temperature range of -40C to +125C. Besides its unique OTP feature, the AD5171 lends itself well to other general-purpose digital potentiometer applications due to its temperature performance, small form factor, and low cost.
