AD5247BKSZ100-2RL7

Digital Potentiometers Overview

The AD5247BKSZ100-2RL7 is a single-channel, 128-position digital potentiometer from Analog Devices. It features a nominal end-to-end resistance of 100 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 and supports an operating temperature range from −40°C to +125°C.

Digital Potentiometers Feature Summary

• 128-position adjustment with linear taper
• I²C-compatible serial interface with hard-coded slave address
• Single-supply operation (2.7 V to 5.5 V)
• Low power consumption (typical 0.9 µA at 3.3 V)

Digital Potentiometers Applications

• Mechanical potentiometer replacement
• Transducer adjustment for pressure, temperature, and optical sensors
• RF amplifier biasing
• LCD brightness and contrast control

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 I²C slave address configuration for the target system design.

Digital Potentiometers Selection Notes

Select this component when a compact, low-power digital solution is needed to replace mechanical potentiometers. The 100 kΩ resistance value and 128-tap resolution are suitable for precision adjustment applications requiring stable performance across a wide industrial temperature range.

Digital Potentiometers Part Context

This part belongs to the AD5247 family of 128-position digital potentiometers. The '100' designation indicates the 100 kΩ end-to-end resistance option. The '2' suffix corresponds to a specific hard-coded I²C slave address, allowing multiple devices to coexist on the same bus alongside other variants.

Digital Potentiometers Replacement Considerations

Direct replacements within the AD5247 series include AD5247BKSZ100-1RL7 and AD5247BKSZ100-RL7. These alternatives share identical electrical specifications but differ in their hard-coded I²C slave addresses.
