DESCRIPTION

The DS1866 Log Trimmer Potentiometer is a single volatile digital potentiometer having eight positions

with a 5-dB resolution per step. The device provides an ideal method for low-cost trimming or volume

control using a CPU or manual control input. The device’s wiper position is set to one of eight positions

by a 3-terminal parallel port. The value of the wiper position is determined by the P0, P1, and P2 port

pins.

The DS1866 is available as a 10k potentiometer and is available in an industrial temperature grade.

Additionally, the DS1866 will operate from 3V or 5V supplies and is ideal for portable applications

requiring low standby current. Two packaging options are available and include the 8-pin (300-mil) DIP,

8-pin (150-mil) SOIC.
