AD5222BRU50-REEL7

Digital Potentiometers Overview

The AD5222BRU50-REEL7 is a dual-channel, 128-position digital potentiometer from Analog Devices. It features two variable resistors with a nominal end-to-end resistance of 50 kΩ and a temperature coefficient of -35 ppm/°C. The device operates on a single supply of 2.7 V to 5.5 V or a dual supply of ±2.3 V to ±2.7 V, consuming a maximum of 40 µA. It utilizes an increment/decrement interface controlled by CS, CLK, and U/D inputs, allowing for push-button operation without a microcontroller. The component is housed in a thin TSSOP-14 package and supports industrial temperatures from -40°C to +85°C.

• Low power consumption of 40 µA maximum

Digital Potentiometers Applications

• Stereo channel audio level control
• Mechanical potentiometer replacement
• Remote incremental adjustment applications
• Instrumentation gain and offset adjustment

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm the reel packaging format and tape specifications. Ensure the procurement source provides valid traceability for the ESD-sensitive components. Cross-reference the part number with the official Analog Devices ordering guide to confirm availability status and any potential obsolescence notices prior to finalizing acquisition.

Digital Potentiometers Selection Notes

Select this model when a 50 kΩ resistance value is required for dual-channel adjustment. The TSSOP-14 package is suitable for space-constrained designs compared to the standard SOIC option. Consider the 40 µA power consumption for battery-operated systems. Verify that the application does not require non-volatile memory, as this device uses volatile storage for wiper position.

Digital Potentiometers Part Context

This component belongs to the AD5222 family of dual digital potentiometers. It serves as an electronic alternative to mechanical pots in test equipment and instrumentation. The 'RU' designation indicates the Thin TSSOP-14 package variant, while '50' specifies the 50 kΩ resistance value. The '-REEL7' suffix denotes the specific reel packaging configuration used for automated surface-mount assembly.

Digital Potentiometers Replacement Considerations

For SPI-compatible interfaces, consider the AD5203, AD5206, AD7376, AD8400, AD8402, or AD8403 series. For non-volatile memory requirements, evaluate the AD5122 or AD514x families. Direct pin-for-pin replacements within the same resistance value are limited to other AD5222 variants with different package options.
