DESCRIPTION
The DS1804 NV Trimmer Potentiometer is a nonvolatile digital potentiometer having 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鈥檚 wiper position is manipulated by a 3-terminal port that provides an increment/
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 10 k鈩? 50 k鈩? and 100 k鈩? The device is
provided in an industrial temperature grade. Additionally, the DS1804 will operate from 3V or 5V
supplies and is ideal for portable application requirements. Three packaging options are available and
include the 8-pin (300-mil) DIP, 8-pin (150-mil) SOIC, 8-pin (118-mil) uSOP, and the Flip Chip
Package.
