AD5248BRMZ10

Digital Potentiometers Overview

The AD5248BRMZ10 is a dual-channel, 256-position digital potentiometer manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7 V to 5.5 V and consumes a maximum supply current of 6 µA. The device features an I²C-compatible interface for full read/write access to the wiper register. Each channel provides a nominal end-to-end resistance of 10 kΩ with a tolerance of ±20% at 25°C and a temperature coefficient of 35 ppm/°C. The unit is housed in a compact 10-lead MSOP package (3 mm × 4.9 mm) and supports an operating temperature range from −40°C to +125°C.

Digital Potentiometers Feature Summary

• Dual-channel architecture with 256 tap positions per channel
• I²C-compatible serial interface with programmable address decode pins (AD0, AD1)
• Low power consumption: 6 µA maximum supply current
• Power-on preset to midscale position

Digital Potentiometers Applications

• Systems calibration
• Electronics level settings
• Mechanical trimmer replacement in new designs
• Transducer adjustment for pressure, temperature, and optical sensors
• RF amplifier biasing and gain control

Digital Potentiometers Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering suffix matches the required resistance value and package type. Check for RoHS compliance status as indicated in official documentation. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to prevent package damage prior to soldering.

Digital Potentiometers Selection Notes

Select this model when dual-channel adjustment is required on a single I²C bus. The AD0 and AD1 pins allow multiple devices to share the same bus lines by setting unique hardware addresses. Compare against the AD5243 if address decoding pins are not needed. Verify that the 10 kΩ resistance value aligns with the circuit's impedance requirements and that the volatile memory type suits the application's power-loss behavior.

Digital Potentiometers Part Context

This component belongs to the AD5243/AD5248 family of high-performance digital potentiometers. The AD5248 variant is distinguished by the inclusion of two additional address decode pins compared to the AD5243. Both devices utilize thin-film technology for stability and low temperature coefficients. The BRMZ10 designation indicates the commercial temperature grade and 10 kΩ resistance value within the MSOP-10 package.

Digital Potentiometers Replacement Considerations

The AD5243BRMZ10 serves as a functional substitute if independent addressing is not required. Other variants in the series include 2.5 kΩ, 50 kΩ, and 100 kΩ resistance options.
