The AD5252BRUZ10 digital potentiometer is designed for processing a range of transducer signals from pressure and temperature sensors to motor velocity and position. It is used in applications such as data acquisition (DAQ)—signal conditioning, communications—modem drivers, industrial—automated test equipment and automotive—calibration. In this article, we will discuss the application field and working principle of the AD5252BRUZ10 digital potentiometer.

The AD5252BRUZ10 operates with a current-based control, that is, it senses the voltage across a low-side load resistor. It provides an adjustable resistance that steps up an input voltage or steps down an output voltage. This adjustable resistance is called digital potentiometer.

AD5252BRUZ10 digital potentiometer has a power Dissipation of 90/45 mW when used in 8-pin/16-pin SOIC package. It has the capability to save up to 256 States with low power dissipation in the OFF latched condition. AD5252BRUZ10 digital potentiometers are highly reliable, providing 100 kHz switchers with a voltage noise of 4 µVrms, a current noise of 10µArms, and a power dissipation of 45mW/90mW.

These digital potentiometers are designed to operate over a temperature range from -40 to +85°C. They are available with an adjustable wiper resistance load of up to 20 kΩ and a maximum supply voltage up to 10 V. The AD5252BRUZ10 has an analog wiper contact, which is a metal oxide slider for any non-latched rotation and an OC contact, which is an optically isolated connection.

The AD5252BRUZ10 is ideal for a wide range of applications as it offers a wide range of features. The digital output enables precision and programmability. The low power dissipation and wide temperature range make it suitable for processes which require long-term stability. An onboard voltage regulator provides fast start-up times with adjustable voltage references.

Once the AD5252BRUZ10 digital potentiometer has been powered up, a digital control word is sent to it which sets the resistance level. The digital control word is written using a serial interface, such as SPI or I2C, which drives the resistance up and down based on the value of the control word. This resistance is referred to as a “setpoint”. The resistance range and the resolution of the resistance setpoint can be adjusted and set accordingly.

The AD5252BRUZ10 offers a wide range of applications because of its precision, low power dissipation, speed, and small size. Some examples of applications include, but are not limited to, data acquisition, motion control, communications, industrial automation, and automotive calibration. For example, in data acquisition, the precision and linearity of the setpoint can be used to condition the signal for accurate and reliable measurement. In industrial automation, the digital output allows for precise control of machinery and robotics.

In conclusion, the AD5252BRUZ10 digital potentiometer is a reliable, high performance, and economical device for a wide range of applications including data acquisition, motion control, communications, industrial automation, and automotive calibration. It is ideal for applications requiring long-term stability due to its low power dissipation and wide temperature range. The device enables precision and programmability, making it a great choice for applications requiring precise control.
