Digipots Enable New Levels of Precision Calibration in Industrial Systems

The ±20% resistor accuracy specifications of all currently available digital potentiometers either limit their use in open-loop applications or add a requirement for the use of calibration techniques.

Ideal for analog engineers who need the capability to precisely adjust signals over a wide voltage range, ADI's new family of 8-bit/10-bit programmable digipots is designed for open-loop applications and systems that demand precision calibration and tolerance matching. Featuring less than 1% end-to-end resistor tolerance error over a wide ±15 V supply range and delivering resistor tolerance performance 20× better than competing digital potentiometers, these devices allow designers to improve system control.

The parts support dual power supplies in the ±10.5 V to ±15 V range and singlesupply operation in the 21 V to 30 V range. The 1024-tap AD5292 and pin-compatible, 256-tap AD5291 feature a 20× programmable wiper memory.

The wiper setting is controlled through an SPI-compatible port. Triggered by a simple software command, no external power supply is required to program—saving on cost and PCB area requirements.

ADIsimDAC™ Online Design Tool Takes the Guesswork Out of Finding the Right DAC for the Job

Analog Devices presents ADIsimDAC, the best online DAC selection tool available today. ADIsimDAC offers a GUI interface that is both intuitive and easy to use. It guides users through six easy steps to deliver an optimized DAC solution. As users navigate each step, they are prompted to answer some basic design questions such as application type (dc control, gain/ leveling, video, etc.), optimized for performances (BOM, INL, DNL, gain, offset, etc.), DAC characteristics (bits, channels, update rate), power supply, and output voltage. Once completed, ADIsimDAC provides you with an optimized DAC solution for your specific application. Get started today by going to www.analog.com/ADIsimDAC.
