The DS1804 NV trimmer potentiometer is a nonvolatile digital potentiometer that has 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 three-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 10k?, 50k?, and 100k?. 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.
