This software application effectively replaces any external I2C controllers, which in turn enhances users’ systems time-to-market. AD5273 is available in 1 k⍀, 10 k⍀, 50 k⍀, and 100 k⍀ in pact SOT23 8-lead standard package and operates from - 40°C to +105°C. Besides its unique OTP feature , the AD5273 lends itself well to general digital potentiometer applications due to its effective resolution, array resistance options, small footprint, and low cost. An AD5273 evaluation kit and software are available. The kit includes the connector and cable that can be converted for further factory programming applications. For applications that require dynamic adjustment of resistance settings with nonvolatile EEMEM, users should refer to AD523x and AD525x families of nonvolatile memory digital potentiometers. GENERAL DESCRIPTION The AD5273 is a 64-position, One-Time-Programmable (OTP) digital potentiometer4 that employs fuse link technology to achieve the permanent program setting. This device performs the...
