DS1804-NV trimmer potentiometer
The DS1804 NV trimmer potentiometer is a non-volatile digital potentiometer with 100 positions. The device provides an ideal method for low-cost trimming applications, using the CPU or manual control inputs with minimal external circuitry. The wiper position of the DS1804 can be stored in EEPROM memory on demand. 3 terminal ports provide an incremental/ Control interface for the down counter that manipulates the wiper position of the device. This port consists of control inputs CS, INC, and U/D. The DS1804 is available in three resistance levels, including a 10kΩ, 50kΩ, and 100kΩ. The device is available in industrial grade temperatures. Additionally, the DS1804 will operate from 3V or 5V supplies and is ideal for portable application requirements. Three packages, including 8-pin DIP (300 mil), 8-pin (150 mil) SOIC, 8-pin (118 mil) uSOP, flip-chip package.
