GENERAL DESCRIPTION

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.

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 new low A-W and B-W resistance feature minimizes

the wiper resistance in the extremes of the resistor array to

typically 45 Ω.

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.

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
