DS1852B-00C+T&R

DS1852B-00C+T&R is an integrated digital potentiometer, which is widely used in commercial, industrial and automotive applications. It is a multi-functional device, suitable for an array of digital and analog circuit applications, like volume control and current setting. This device offers an ideal solution for substituting mechanical potentiometers. This integrated potentiometer contains a dual-channel (A and B) digitally controlled resistive element and an on-board temperature sensor.

Application Field

The DS1852B-00C+T&R provides a reliable solution for digital control of a resistance value in various applications. Furthermore, its power source comes from the resistance terminals, which simplifies the wiring and controls. The most common applications of this device include data acquisition systems, process control systems, motor speed and torque control systems, programmable logic controllers, and user control panels.

Working Principle

The DS1852B-00C+T&R works by adjusting the external circuit resistance through two precision resistor arrays and also measuring temperature through a temperature sensor. The resistance values of the arrays are digitally committed by a serial interface and data access. But the range of the resistances is limited from 0-5KΩ. Any change in resistance value is done by the command through the serial interface, and the changes are digitally analyzed by the MCU. In addition, the device integrates a temperature sensor that is capable of measuring the temperature form 0° to 150°C ±1°C accuracy.

Moreover, DS1852B-00C+T&R utilizes a non-volatile memory, which permits the device to save two resistance values, corresponding to two different temperatures. This enables the user to set two temperatures and the resistance values in between the two would be automatically adjusted depending upon the temperature readings. In addition, it is equipped with a power-on-reset feature to reset the device upon the power supply.

Overall, DS1852B-00C+T&R is an excellent device to achieve multi-functionality in different applications. It offers advanced features like excellent accuracy, low power consumption, and low cost. Furthermore, this device is a highly reliable and advanced integrated digital potentiometer and temperature sensor.
