GENERAL DESCRIPTION

The

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

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.
