AD5247BKS5-R2

Digital Potentiometers Overview

The AD5247BKS5-R2 is a single-channel, 128-position digital potentiometer from Analog Devices. It features an I²C-compatible interface for full read/write access to the wiper register. The device offers a nominal end-to-end resistance of 5 kΩ with a linear taper and a low temperature coefficient of 45 ppm/°C. Operating on a single supply voltage ranging from 2.7 V to 5.5 V, it consumes a typical supply current of 3 μA. The unit 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 resistance
• I²C-compatible serial interface with full read/write capability
• Low power consumption: 3 μA typical supply current
• Wide operating temperature range: –40°C to +125°C

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 against the manufacturer's official documentation to confirm packaging details such as reel or cut tape quantities. Confirm that the selected variant matches the required slave address configuration for the target I²C bus topology. Ensure compatibility with the system's voltage levels and thermal requirements before finalizing procurement.

Digital Potentiometers Selection Notes

Select this component when a compact solution for variable resistance adjustment is required. The 5 kΩ resistance value suits applications needing moderate current handling. Verify that the I²C bus speed does not exceed the specified 400 kHz limit. Consider the volatile memory type if power loss retention of the wiper setting is not required, noting the power-on preset to midscale feature.

Digital Potentiometers Part Context

This part belongs to the AD5247 family of 128-position digital potentiometers. Other variants in the series offer different resistance values (10 kΩ, 50 kΩ, 100 kΩ) and packaging options. The BKS5 designation specifically indicates the 5 kΩ resistance value and the SC-70-6 package style within the Analog Devices portfolio.

Digital Potentiometers Replacement Considerations

Direct replacements include other AD5247 variants with matching resistance and package, such as AD5247BKSZ5-RL7. Ensure any substitute maintains the same I²C slave address configuration and pinout compatibility.
