AD5247BKS100-RL7

Digital Potentiometers Overview

The AD5247BKS100-RL7 is a single-channel, 128-position digital potentiometer from Analog Devices. It features an end-to-end resistance of 100 kΩ with a ±20% tolerance 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 3 μA. It utilizes an I²C-compatible interface for full read/write access to the wiper register. The unit is housed in an ultracompact SC-70-6 package and supports a wide operating temperature range from –40°C to +125°C.

Digital Potentiometers Feature Summary

• 128-position adjustment with linear taper
• I²C-compatible serial interface with full read/write capability
• Single-supply operation (2.7 V to 5.5 V) with low power consumption (3 μA typical)
• 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 against the manufacturer's official documentation to confirm pinout compatibility and packaging type. Ensure the selected variant matches the required nominal resistance value and slave address configuration for the target I²C bus topology.

Digital Potentiometers Selection Notes

Select this component for applications requiring compact size and precise digital resistance control. The 100 kΩ option is suitable for high-impedance circuits. Note that the 10 kΩ and 100 kΩ variants offer three hard-coded slave addresses, facilitating multiple devices on a single bus without external address pins.

Digital Potentiometers Part Context

This part belongs to the AD5247 family of 128-position digital potentiometers. Other variants in the series include 5 kΩ, 10 kΩ, and 50 kΩ resistance options. The family shares identical pinouts and functional characteristics, differing primarily in nominal resistance values and available I²C slave address configurations.

Digital Potentiometers Replacement Considerations

Direct substitutes within the same family include AD5247BKS5-RL7, AD5247BKS10-RL7, and AD5247BKS50-RL7. These parts share the same package, interface, and functionality but differ in end-to-end resistance values.
