AD5247BKSZ5-RL7

Digital Potentiometers Overview

The AD5247BKSZ5-RL7 is a single-channel, 128-position digital potentiometer manufactured by Analog Devices. It features an end-to-end resistance of 5 kΩ with a linear taper and a temperature coefficient of 45 ppm/°C. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, consuming a typical supply current of 0.9 µA at 3.3 V. It utilizes an I²C-compatible interface for full read/write access to the wiper register. The component is housed in an ultracompact SC-70-6 package and supports an operating temperature range from −40°C to +125°C.

Digital Potentiometers Feature Summary

• 128-position adjustment with 5 kΩ nominal end-to-end resistance
• I²C-compatible serial interface supporting full read/write operations
• Low power consumption: 0.9 µA typical at 3.3 V supply
• Power-on preset to midscale position

Digital Potentiometers Applications

• Mechanical potentiometer replacement in new designs
• Transducer adjustment for pressure, temperature, position, chemical, and optical sensors
• RF amplifier biasing
• LCD brightness and contrast adjustment
• Gain control and offset adjustment

Digital Potentiometers Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging format required for production integration. Confirm that the 5 kΩ resistance variant matches the circuit design specifications. Ensure compatibility with the target I²C bus addressing scheme, as this model shares a fixed slave address within the AD5247 family.

Digital Potentiometers Selection Notes

Select this component when a compact, low-power digital solution is required to replace mechanical potentiometers. The 5 kΩ resistance value is suitable for applications requiring moderate current handling. Verify that the system can accommodate the volatile memory nature of the wiper setting, which resets to midscale upon power-up but loses state during power cycles unless maintained by constant bias.

Digital Potentiometers Part Context

This part belongs to the AD5247 series of 128-position I²C-compatible digital potentiometers. The 'BKSZ5' designation indicates the 5 kΩ resistance option packaged in an SC-70-6 footprint. Other variants in the series offer 10 kΩ, 50 kΩ, and 100 kΩ options, with some providing multiple hard-coded slave addresses for multi-device bus configurations.

Digital Potentiometers Replacement Considerations

Direct replacements include other AD5247 variants with different resistance values (e.g., AD5247BKSZ10-RL7) if the resistance tolerance allows. For pin-compatible alternatives with different features, consult the Analog Devices digital potentiometer portfolio, ensuring I²C compatibility and package dimensions match.
