Data acquisition systems are used to measure, filter, store, and acquire data from various kinds of systems, including industrial machines and laboratory instruments. Digital potentiometers are devices used to control the voltage or current in an analog circuit by varying the resistance in the circuit. The DS1267BE-100+ is a digital potentiometer used for such applications. It has a low profile surface mount compatible package and is suitable for a wide range of applications, from industrial measurement to laboratory experimentation.

The DS1267BE-100+ is a non-volatile, analog-taper digital potentiometer with 64 taps. It has a 1-wire, serial data interface controlled by the SPI logic protocol. The 1-wire allows the potentiometer to be connected directly to a controller or processor, eliminating the need for an additional bus connection. The device has a slave select pin that allows it to be connected to up to eight potentiometers in parallel, reducing the number of connections needed. The DS1267BE-100+ is designed to operate from a single 3V to 5V power supply and operates at a temperature range of -40° to 125° C.

The DS1267BE-100+ works by using a digital potentiometer to adjust the resistance in the circuit. The resistance is controlled by a variable resistance element, or tap, which is connected to a switch that can control the connection between the tap and a reference voltage. The tap is configured to connect to one end of the switch, while the other end of the switch is connected to the reference voltage. The output voltage of the potentiometer is determined by the ratio between the switch resistance and the tap resistance.

The digital potentiometer is controlled by the 1-wire digital interface. When the SPI logic is enabled, the tap can be selected and the resistance of the tap adjusted accordingly. The tap is programmed to connect to the appropriate reference voltage, which will determine the voltage output of the potentiometer. The resistance of the tap is then adjusted until the desired output voltage is obtained.

The DS1267BE-100+ is a versatile device which can be used in a wide range of applications. Its low profile surface mount compatible package makes it ideal for industrial measurement and laboratory experimentation. Its 1-wire serial data interface allows it to be connected directly to a controller or processor, eliminating the need for additional bus connections. Its adjustable resistance range, low current consumption, and wide temperature range make it a reliable and effective digital potentiometer.
