AD5247BKSZ100-1RL7

Digital Potentiometers Overview

The AD5247BKSZ100-1RL7 is a single-channel, 128-position digital potentiometer from Analog Devices. It features a nominal end-to-end resistance of 100 kΩ with a linear taper and ±20% tolerance. 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 100 kΩ nominal resistance
• I²C-compatible serial interface with hard-coded slave address
• Low power consumption: 0.9 µA typical at 3.3 V
• Wide operating temperature range: −40°C to +125°C

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 that the I²C slave address configuration aligns with system bus requirements, as this variant includes a specific hard-coded address option distinct from other resistance values in the series.

Digital Potentiometers Selection Notes

Select this component when a compact, low-power digital solution is required for precise resistance adjustment. The 100 kΩ value suits applications requiring higher impedance levels. Verify that the system I²C clock frequency does not exceed 400 kHz and that the supply voltage remains within the 2.7 V to 5.5 V range for optimal performance.

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 options, which share similar electrical characteristics but differ in nominal resistance and available I²C slave addresses. The BKSZ designation indicates the SC-70-6 surface-mount package.

Digital Potentiometers Replacement Considerations

Direct replacements within the same family include AD5247BKSZ100-RL7 and AD5247BKSZ100-R2. Note that these alternatives may have different I²C slave addresses or packaging suffixes; verify electrical parameters and pin compatibility before substitution.
