AD5247BKSZ10-2RL7

Digital Potentiometers Overview

The AD5247BKSZ10-2RL7 is a single-channel, 128-position digital potentiometer from Analog Devices. It features a nominal end-to-end resistance of 10 kΩ with a ±20% tolerance and a temperature coefficient of 45 ppm/°C in rheostat mode. 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 unit is housed in an ultracompact SC-70-6 package (2 mm × 2.1 mm) and supports an operating temperature range from −40°C to +125°C.

Digital Potentiometers Feature Summary

• 128-position adjustment with linear taper and volatile memory
• I²C-compatible serial interface with hard-coded slave address 0x26 (binary 0010110)
• Single-supply operation from 2.7 V to 5.5 V with low power consumption
• 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 '-2RL7' against the manufacturer's official documentation to confirm the exact reel packaging quantity and tape specifications. Confirm that the hard-coded slave address associated with the '2' suffix matches the system bus requirements, as this variant differs from standard 'RL7' versions.

Digital Potentiometers Selection Notes

Select this component when a compact, digitally controlled variable resistor is required for applications needing 128 distinct resistance steps. Ensure the system I²C bus can accommodate the specific slave address assigned to the '2' suffix variant. Verify that the 10 kΩ nominal resistance and ±20% tolerance align with the circuit's precision requirements.

Digital Potentiometers Part Context

This part belongs to the AD5247 family of 128-position digital potentiometers. The '10' in the model number indicates a 10 kΩ nominal resistance. The 'BKSZ' designation refers to the SC-70-6 package type. The final digit in the suffix typically denotes one of three hard-coded slave addresses available for the 10 kΩ version, allowing multiple devices on a single bus.

Digital Potentiometers Replacement Considerations

Direct pin-for-pin replacements within the same family include AD5247BKSZ10-1RL7 and AD5247BKSZ10-RL7. Note that these alternatives utilize different hard-coded I²C slave addresses; system software must be updated to match the address of the substitute part.
