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.
