DESCRIPTION
The DS1804 is a nonvolatile digital potentiometer hav-
ing 100 positions. The device provides an ideal method
for low–cost trimming applications using a CPU or
manual control input with minimal external circuitry.
Wiper position of the DS1804 can be stored in EEPROM
memory on demand. The device’s wiper position is
manipulated by a 3–terminal port that provides an incre-
ment/decrement counter controlled interface. This port
consists of the control inputs CS, INC, and U/D.
The DS1804 is available in three resistor grades which
include a 10K
, 50K
, and 100K
. The device is pro-
vided in an industrial temperature grade. Additionally,
the DS1804 will operate from 3V or 5V supplies and is
ideal for portable application requirements. Two pack-
aging options are available and include the 8–pin (300
mil) DIP and 8–Pin (150 mil) SOIC.
