AD5246BKSZ10-RL7

Digital Potentiometers Overview

The AD5246BKSZ10-RL7 is a single-channel, 128-position digital potentiometer from Analog Devices. It features an end-to-end resistance of 10 kΩ with a nominal tolerance of ±30% 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. Packaged in an ultracompact SC-70-6 (2 mm × 2.1 mm) format, it 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
• Low power consumption: 0.9 µA typical at 3.3 V
• Ultracompact SC-70-6 package

Digital Potentiometers Applications

• Mechanical potentiometer replacement
• Transducer adjustment for pressure, temperature, position, chemical, and optical sensors
• RF amplifier biasing
• Gain control and offset adjustment

Digital Potentiometers Procurement Notes

Verify the specific resistance value suffix (10 for 10 kΩ) and packaging option (RL7 for reel) against the official Analog Devices ordering guide. Confirm RoHS compliance status as indicated by the 'Z' suffix in the part number. Ensure the I²C slave address configuration matches system requirements before integration.

Digital Potentiometers Selection Notes

Select this component when a compact, low-power digital solution is required for variable resistance adjustments. The 10 kΩ resistance value suits applications requiring moderate impedance levels. Verify that the system voltage falls within the 2.7 V to 5.5 V range and that the I²C bus speed does not exceed 400 kHz. Consider the ±30% initial tolerance if high precision is not critical.

Digital Potentiometers Part Context

This part belongs to the AD5246 family of 128-position digital potentiometers. Other variants in the series include 5 kΩ, 50 kΩ, and 100 kΩ resistance options, such as the AD5246BKSZ5-RL7 and AD5246BKSZ50-RL7. All share the same SC-70-6 package and I²C interface characteristics.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include AD5246BKSZ5-RL7 (5 kΩ), AD5246BKSZ50-RL7 (50 kΩ), and AD5246BKSZ100-RL7 (100 kΩ). These parts are pin-compatible but differ in end-to-end resistance values.
