AD5247BKS50-R2

Digital Potentiometers Overview

The AD5247BKS5-R2 is a single-channel, 128-position digital potentiometer manufactured by Analog Devices Inc. It features an end-to-end resistance of 5 kΩ with a linear taper and operates on a single supply voltage ranging from 2.7 V to 5.5 V. The device utilizes an I²C-compatible interface for full read/write access to the wiper register. Key electrical specifications include a typical supply current of 3 μA, a temperature coefficient of 45 ppm/°C, and an operating temperature range from –40°C to +125°C. It is housed in an ultracompact SC-70-6 package.

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 with 3 μA typical supply current
• Power-on preset to midscale position

Digital Potentiometers Applications

• Mechanical potentiometer replacement in new designs
• Transducer adjustment for pressure, temperature, 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 against the manufacturer's current datasheet to confirm packaging type and lead time requirements. Ensure compatibility with the target I²C bus voltage levels and check for any regional distribution restrictions or obsolescence notices prior to finalizing procurement plans.

Digital Potentiometers Selection Notes

Select this component when a compact solution for variable resistance adjustment is required in battery-operated devices due to its low supply current. The 5 kΩ resistance value and 128 taps provide sufficient resolution for many analog control applications. Confirm that the SC-70-6 package dimensions fit the available PCB space and that the I²C address conflicts are managed if multiple devices share the bus.

Digital Potentiometers Part Context

This part belongs to the AD5247 family of digital potentiometers, which offers various resistance values including 10 kΩ, 50 kΩ, and 100 kΩ options. The BKSZ suffix indicates a Pb-free SC-70-6 package, while the R2 suffix typically denotes reel packaging. The device shares functional similarities with the AD5246 but differs in interface capabilities and pinout configurations.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include AD5247BKS5-RL7 and AD5247BKSZ5-RL7, which offer identical electrical characteristics but may differ in packaging quantity or tape-and-reel specifications. Verify pin compatibility and I²C addressing before substitution.
