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.
