AD5254BRUZ50 Digital Potentiometer by Analog Devices Inc.

The AD5254BRUZ50, manufactured by Analog Devices Inc., is a precision digital potentiometer that offers a reliable and versatile solution for a wide array of applications requiring variable resistance adjustments. This component is a part of the high-performance digital potentiometer series that Analog Devices is known for, which combines industry-leading technology with robust functionality.

With a resistance value of 50 kΩ, the AD5254BRUZ50 provides four independently programmable channels, allowing for fine-tuning of resistance settings in complex circuits without the need for manual potentiometer adjustments. The digital interface of this potentiometer facilitates easy integration into microcontroller-based systems, making it an ideal choice for automated adjustments in response to varying environmental conditions or system requirements.

Key Features:

• Resistance: 50 kΩ across four channels
• Interface: I²C-compatible serial interface
• Resolution: 256 positions for each potentiometer
• Package: 16-lead TSSOP (Thin Shrink Small Outline Package)
• Supply Voltage: Operates from a 2.7 V to 5.5 V single supply
• Temperature Range: Industrial range (-40°C to +105°C)
• Nonvolatile Memory: On-chip memory to store the wiper position for automatic recall on power-up
• Endurance: 1 million wiper changes per potentiometer channel
• Data Retention: 50 years

The AD5254BRUZ50's nonvolatile memory ensures that the last position of the wiper is recalled upon power-up, eliminating the need for recalibration after each power cycle. This feature is particularly useful in applications such as calibration settings, device configuration, and system controls where the potentiometer setting needs to be retained even after the device is turned off.

Its compact TSSOP package makes the AD5254BRUZ50 suitable for space-constrained applications, while its robust operating temperature range ensures reliable performance in challenging environmental conditions. Whether used in industrial controls, automotive systems, consumer electronics, or communication devices, the AD5254BRUZ50 from Analog Devices Inc. represents a smart choice for designers looking for a digital potentiometer with high precision and flexibility.
