Data Acquisition – Digital Potentiometers

Digital potentiometers provide an easy, cost-effective way to control the extent of a device’s operation. They are effectively used to adjust voltage to a device, adjust the magnitude of a voltage signal, or build adjustable voltage dividers. Digital potentiometers are available in various sizes and configurations and are used for various industries and applications such as precision medical equipment, WiFi signal boosters, and automotive audio systems.

The DS1267BS-100+ is one type of digital potentiometer that offers a range of features to serve the needs of many applications. It has a digital, non-volatile, electronically adjustable linear taper with a range up to 70V. The digital control signal is a 3 wire SPI interface, with CS, UP/DOWN and Serial Data outputs and it is compatible with all 5V industry standards. This device is designed to provide a precisely regulated voltage level to any load (without the use of a mechanical rotary switch) over the required range of voltage, with high accuracy and minimum noise.

The DS1267BS-100+ is mainly used for systems that require fine adjustment of the current or voltage levels, such as Motor Control, Voltage Regulation Process Control, Audio Equipment and Security Systems. Its ability to adjust the output voltage without any mechanical movement makes it highly preferred in these areas. Moreover, due to its low power consumption, compact size and accuracy, it is suitable for precision applications.

The DS1267BS-100+ has two operation modes: static and pulsed. In static mode, the output voltage can be adjusted by setting the UP/DOWN pin. In the case of pulsed mode, the DS1267BS-100+ can be programmed as a master-slave configuration where the master adjusts the pulse width. This simplifies the system configuration, as it eliminates the need for an external controller.

The working principle of the DS1267BS-100+ is quite simple. The device is equipped with an internal voltage reference, DAC, and operational amplifier. The digital input is then converted to a voltage reference by the DAC, which is then amplified by the operational amplifier and sent to the output terminal. The output voltage can be adjusted by setting the UP/DOWN pin between 0V and 5V. Furthermore, the internal reference source can be adjusted by increasing or decreasing the reference voltage up to a maximum voltage.

The DS1267BS-100+ is highly versatile and can be used in a wide variety of applications requiring precise regulation of its output voltage. Its simple working principle and easily adjustable UP/DOWN switch makes it ideal for precision control applications. With its high accuracy, low power consumption and compact size, the DS1267BS-100+ is sure to be an essential part of any system that requires precise voltage regulation.
