AD5253BRUZ1-RL7

Digital Potentiometers Overview

The AD5253BRUZ1-RL7 is a quad-channel, I2C-compatible digital potentiometer featuring 64-position resolution and nonvolatile memory (EEMEM). It operates on a single supply of 2.7 V to 5.5 V or dual supplies of ±2.25 V to ±2.75 V. The device includes four independent RDACs with wiper settings stored in EEMEM for power-on restoration within 300 µs. It supports direct read/write access to registers, predefined increment/decrement commands, and ±6 dB step changes. The component is housed in a TSSOP-20 package and functions over an extended industrial temperature range from –40°C to +105°C.

Digital Potentiometers Feature Summary

• Quad-channel architecture with 64-step linear resolution per channel
• Nonvolatile EEMEM stores wiper positions and resistance tolerance data
• I2C interface with two slave address-decoding bits for multi-device bus operation
• Supports synchronous/asynchronous updates and wiper setting readback

Digital Potentiometers Applications

• Mechanical potentiometer replacement
• RGB LED backlight control
• Programmable gain and offset control
• Sensor calibrations

Digital Potentiometers Procurement Notes

Verify the specific resistance value suffix associated with the BRUZ1 designation against official Analog Devices documentation, as standard variants include 1 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ options. Confirm that the RL7 suffix corresponds to the required reel packaging format. Ensure compatibility with the host system's I2C voltage levels and pull-up requirements before integration.

Digital Potentiometers Selection Notes

Select this component when a quad-channel digital solution with persistent memory is required. The AD5253 variant provides 64 positions; choose the AD5254 if 256 positions are needed. Verify that the nominal resistance value meets the circuit's impedance requirements. Consider the 4 MHz bandwidth of the 1 kΩ version versus lower bandwidths for higher resistance values when designing high-speed signal paths.

Digital Potentiometers Part Context

This part belongs to the AD5253/AD5254 family of I2C Nonvolatile Memory Digital Potentiometers. It serves as a solid-state alternative to mechanical trimmers and variable resistors. The device integrates patented resistance-tolerance storage, allowing users to retrieve absolute end-to-end resistance values from the EEMEM for precision applications requiring calibration data retention.

Digital Potentiometers Replacement Considerations

Direct functional substitutes within the same family include the AD5254 series for increased resolution. For pin-compatible alternatives with different specifications, consult the manufacturer's cross-reference guide. Ensure any replacement maintains the I2C protocol compatibility and nonvolatile memory functionality if power-on state retention is critical.
