The DS1805E-010+T&R is able to provide very high precision with crystal-controlled step accuracy down to 0.1%. This digital potentiometer is also able to provide full linearity, with adjustable gain and offset capabilities. The step size of the potentiometer can be adjusted from 1 µA to 100 µA depending on the application.

The DS1805E-010+T&R is a 10-turn, dual-output digital potentiometer that is remotely adjustable over a wide range. The two digital outputs are adjustable separately and can be map to any arbitrary non-linear transfer function. The digital outputs of this device are also fully buffered, so they remain stable even when multiple devices are connected in parallel.

Working Principle

The DS1805E-010+T&R is a digital potentiometer that creates an analog voltage with a digital input. The device works by utilizing digital memory to store and recall analog voltages that are set by the user. The memory stores analog voltages which are then applied to the wiper via an independent voltage source.

The DS1805E-010+T&R is a resistor-based device. It is operated by supplying constant current to the wiper terminal, which then creates a voltage-dependent resistance. The resistance value is dependent on the wiper position. This resistance value is then converted to a linear voltage output by the analog to digital converter (ADC).

The DS1805E-010+T&R is specifically designed for high accuracy data acquisition applications. The output of this device is highly linear and offers good accuracy and long-term repeatability. The internal circuitry of this device is designed to operate with very low noise and distortion levels.

The DS1805E-010+T&R has a wide range of applications, such as resistive bridge, bridge bridge balance, or precision measurement and control. This digital potentiometer is ideal for applications that require precision, accuracy, and high linearity, such as calibration of electronic loading systems in process control and automated testing systems.

In conclusion, the DS1805E-010+T&R is a digital potentiometer that provides high accuracy, repeatability, and linearity. Its 10-turn dual-output design makes it ideal for calibration applications and precision measurement and control. The device works by supplying constant current to the wiper terminal and converting this resistance to a linear voltage output by the ADC.
