DS1804 Overview

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. The DS1804 is available in three resistor grades, which include a 10kΩ, 50kΩ, and 100kΩ. 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 mils) DIP, 8-pin (150 mils) SO, and 8-pin (118 mils) μSOP.

The DS1804 is a single nonvolatile potentiometer. The device has a total of 100 tap-points including the L- and H- terminals. A total of 99 resistive segments exist between the L- and H- terminals. These tappoints are accessible to the W-terminal, whose position is controlled via a three-terminal control port. The DS1804 can be easily used as an OTP device. The user of the DS1804 can trim the desired value of the wiper position and set this position for storage as described above.

This article provides you with a basic overview of the DS1804 NV Trimmer Potentiometer, including its pin descriptions, features and specifications, etc., to help you quickly understand what DS1804 is.

Frequently Asked Questions

What is the power-on process of DS1804? Please describe in detail.
On power-up, the DS1804 will load the value of EEPROM memory into the wiper position register (or 1 of 100 decoder). The value of this register can then be set to another wiper position if desired, by using the three-terminal control port. On power-up, wiper position will be loaded within a maximum time period of 500µs once the power-supply is stable. Additionally, the three-terminal interface port will be active after 50ms.
Regarding DS1804, will wiper position register data be lost during a power outage?
On power-down, the wiper position register data will be lost. On the next device power-up, the value of EEPROM memory will be loaded into the wiper position register.
What is the wear state of DS1804? Will the DS1804 still function after wear and tear?
The DS1804 is specified to accept 50,000 writes to EEPROM over 0°C to 70ºC before a wear-out condition. After wear-out the DS1804 will still function and wiper position can be changed during powered conditions using the three-terminal control port. However, on power-up the wiper-position will be indeterminate.
