The AD is a dual-channel, I 2 C, nonvolatile memory, digitally controlled potentiometer with 64 positions. These devices perform the same electronic adjustment functions as mechanical potentiometers, trimmers, and variable resistors.
Once the settings are stored, they are restored automatically to the RDAC registers at system power-on; the settings can also be restored dynamically. These functions are useful for steep-slope, nonlinear adjustments, such as white LED brightness and audio volume control.
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist. In addition, the AD uses a versatile I 2 C serial interface that operates in fast mode, allowing speeds of up to kbps and supporting the selection of up to four different I 2 C addresses. Complete specifications for the AD part can be found in the AD data sheet.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well.
