Product Details

The AD5116 provides a nonvolatile digital potentiometer solution for 64-position adjustment applications, offering guaranteed low resistor tolerance errors of ±8% and up to ±6 mA current density in the A, B, and W pins. The low resistor tolerance, low nominal temperature coefficient, and high bandwidth simplify open-loop applications, as well as tolerance matching applications.

The new low A-W and B-W resistance feature minimizes the wiper resistance in the extremes of the resistor array to typically 45 Ω.

A simple push button interface allows manual control with just two external push button switches. The AD5116 is designed with a built-in adaptive debouncer that ignores invalid bounces due to contact bounce (commonly found in mechanical switches). The debouncer is adaptive, accommodating a variety of push buttons.

The AD5116 can automatically save the last wiper position into EEPROM, making it suitable for applications that require a power-up in the last wiper position, for example, audio equipment.

The AD5116 is available in a 2 mm × 2 mm 8-lead LFCSP package. The part is guaranteed to operate over the extended industrial temperature range of −40°C to +125°C.
