Along with its unique OTP feature, the AD5273BRJ10-R2 lends itself well to general digital potentiometer applications due to its effective resolution, array resistance options, small footprint, and low cost.
An AD5273BRJ10-R2 evaluation kit and software are available. The kit includes the connector and cable that can be converted for factory programming applications.
For applications that require dynamic adjustment of resistance settings with nonvolatile EEMEM, refer to the AD5231, AD5232, AD5233, and AD5235 family, and the AD5251, AD5252, AD5254, AD5258, and AD5259 family of nonvolatile memory digital potentiometers.
