AD5246BKS50-R2

Digital Potentiometers Overview

The AD5246BKS50-R2 is a single-channel, 128-position digital resistor manufactured by Analog Devices Inc. It features an end-to-end resistance of 50 kΩ and operates via an I²C-compatible interface. The device supports a supply voltage range of 2.7 V to 5.5 V with a typical supply current of 0.9 µA at 3.3 V. It utilizes a compact SC-70-6 package and provides full read/write access to the wiper register. The unit is rated for operation between -40°C and +125°C.

Digital Potentiometers Feature Summary

• 128-position adjustment with linear taper
• I²C compatible serial interface with full read/write capability
• Ultracompact SC-70-6 (2 mm × 2.1 mm) package
• Low power consumption: 0.9 µA typical at 3.3 V

Digital Potentiometers Applications

• Mechanical potentiometer replacement in new designs
• 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 ordering suffix 'R2' against the manufacturer's official documentation to confirm tape-and-reel specifications. Confirm RoHS compliance status as indicated by the 'Z' designation in similar part numbers within the series.

Digital Potentiometers Selection Notes

Select this component when a 50 kΩ nominal resistance is required for space-constrained applications. Ensure the system voltage remains within the 2.7 V to 5.5 V range. Consider the 0.9 µA typical current draw for battery-operated designs requiring minimal quiescent power.

Digital Potentiometers Part Context

This component belongs to the AD5246 family of 128-position I²C-compatible digital resistors. The family includes variants with 5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ resistance values. All variants share the same pinout, interface protocol, and physical package dimensions.

Digital Potentiometers Replacement Considerations

Direct replacements include other AD5246 variants with different resistance values if the circuit allows. Cross-brand alternatives must match the 128-position resolution, I²C interface, and SC-70-6 package constraints.
