AD5253BRUZ10

Digital Potentiometers Overview

The AD5253BRUZ10 is a quad-channel, I2C-compatible digital potentiometer featuring 64-position resolution and nonvolatile memory. It offers a nominal resistance of 10 kΩ with ±20% tolerance and a temperature coefficient of 650 ppm/°C. The device operates on a single supply from 2.7 V to 5.5 V or dual supplies of ±2.25 V to ±2.75 V. It includes four independent rheostats/potentiometers in a 20-TSSOP package, supporting direct read/write access to RDAC and EEMEM registers for wiper settings and user-defined data.

Digital Potentiometers Feature Summary

• Quad-channel architecture with 64-step linear adjustment per channel
• Nonvolatile EEMEM stores wiper positions and resistance tolerance data
• I2C serial interface with two slave address bits for multi-device bus operation
• Supports synchronous/asynchronous updates and predefined ±6 dB step commands

Digital Potentiometers Applications

• Mechanical potentiometer replacement in embedded systems
• RGB LED backlight control and white LED brightness adjustment
• Programmable gain and offset control in signal conditioning circuits
• Sensor calibration and programmable voltage-to-current conversion

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm pinout compatibility and electrical specifications. Confirm that the required resistance tolerance and temperature coefficient meet the design constraints. Check for availability of evaluation boards if hardware validation is necessary before production integration.

Digital Potentiometers Selection Notes

Select this component when a quad-channel solution with nonvolatile memory retention is required. Ensure the system supports I2C communication at frequencies up to 400 kHz. Verify that the 10 kΩ resistance value aligns with the target impedance requirements, as bandwidth decreases with higher resistance values compared to the 1 kΩ variant.

Digital Potentiometers Part Context

This part belongs to the AD5253 family, which provides 64-position resolution, distinct from the AD5254 family offering 256 positions. The BRU suffix indicates a specific temperature grade and packaging option within the Analog Devices portfolio. It serves as a solid-state alternative to mechanical trimmers in space-constrained PCB designs.

Digital Potentiometers Replacement Considerations

The AD5254BRUZ10 provides identical pinouts and functionality but offers 256-position resolution instead of 64. Other variants in the series include different resistance values such as 1 kΩ, 50 kΩ, and 100 kΩ.
