The AD5293BRUZ-50-RL7 is a Digital Potentiometer from Analog Devices that is used for Data Acquisition applications. This device is a monolithic CMOS (Metal-Oxide-Semiconductor) integrated circuit that is an ideal solution for providing digitally programmable resistance adjustments in a wide range of applications. The Digital Potentiometer has a wide variety of uses including programmable voltage dividers, filter circuit trims, level shifters, and other applications requiring adjustable resistance.

The AD5293BRUZ-50-RL7 has a total adjustable resistance of 50kΩ that is spread over 128 steps. The device is capable of operating over a wide range of voltage supply (2.7V to 5.5V) and temperature (-40 Celsius to 125 Celsius). It also has an input voltage rating of 0V to VDD and an output voltage rating of 0V to VDD.

The AD5293BRUZ-50-RL7 works by using two separate logic circuits, one to select the wiper position and one to shift the wiper output. The wiper selection is controlled by applying a voltage to one of the three address pins, A0, A1, and A2. Each address pin can represent one of four binary values – 0 V, 1 V, 2 V or 3 V. These three address pins are then used to address the wiper to one of the 128 available resistance values on the Digital Potentiometer.

The output from the wiper is then shifted out of the device through the CS pin. The CS pin is held low during the shifting operation. This is determined via the CS polarity set pin which determines whether the CS pin is held low or high during the shifting process. Once the shifting process is complete, the CS pin is brought high as soon as the last bit has been shifted out of the Digital Potentiometer.

The AD5293BRUZ-50-RL7 is an ideal solution for applications requiring adjustable resistance in a range of devices and systems. This Digital Potentiometer is versatile and extremely cost-effective as it enables users to adjust resistance values in any desired increments over a wide temperature and voltage range. Its robust functionality makes it suitable for a broad range of applications.
