AD5222BRUZ10-REEL7

Digital Potentiometers Overview

The AD5222BRUZ10-REEL7 is a dual-channel, 128-position digital potentiometer manufactured by Analog Devices. It features two independent variable resistors with a nominal end-to-end resistance of 10 kΩ and a temperature coefficient of -35 ppm/°C. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V or a dual supply of ±2.3 V to ±2.7 V. Control is managed via a simple increment/decrement interface using Chip Select (CS), Clock (CLK), and Up/Down (U/D) inputs, eliminating the need for microcontrollers in push-button applications. It is housed in a 14-lead Thin Shrink Small Outline Package (TSSOP).

Digital Potentiometers Feature Summary

• Dual-channel architecture with 128 programmable positions per channel.
• Increment/Decrement control interface compatible with mechanical switches.
• Low power consumption with maximum supply current of 40 µA.
• Common mode operation preserves relative wiper settings during adjustment.

Digital Potentiometers Applications

• Stereo channel audio level control.
• Mechanical potentiometer replacement in instrumentation.
• Remote incremental adjustment systems.
• Programmable gain and offset adjustment circuits.

Digital Potentiometers Procurement Notes

Verify the specific suffix 'REEL7' indicates tape and reel packaging when sourcing components. Confirm the 'BRU' designation corresponds to the TSSOP-14 package variant rather than the standard SOIC-14. Ensure compatibility with the required 10 kΩ resistance value for the target circuit design.

Digital Potentiometers Selection Notes

Select this model for applications requiring precise electronic adjustment without volatile memory retention. The 10 kΩ resistance value offers a balance between bandwidth and power dissipation. Consider the TSSOP-14 package for space-constrained designs compared to the larger SOIC-14 option available in the same series.

Digital Potentiometers Part Context

This component belongs to the AD5222 family of dual digital potentiometers. It serves as an electronic alternative to mechanical pots, specifically optimized for instrument and test equipment front-panel interfaces. The BRU10 variant specifies the 10 kΩ resistance value within the thin TSSOP-14 package format.

Digital Potentiometers Replacement Considerations

For SPI-compatible interfaces, consider the AD5203, AD5206, AD7376, or AD8400 series. For non-volatile storage requirements, the AD5122 or AD5142 families are suitable alternatives. Direct pin-for-pin replacement requires matching the terminal resistance value and package type.
