AD5241BR10

Digital Potentiometers Overview

The AD5241BR10 is a single-channel, 8-bit digital potentiometer from Analog Devices. It provides 256 programmable resistance positions with a nominal value of 10 kΩ and a temperature coefficient of 30 ppm/°C. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V or dual supplies of ±2.7 V. It features an I²C-compatible serial interface for wiper position programming and includes two additional programmable logic outputs (O1, O2). The unit incorporates an internal power-on midscale preset and a self-contained shutdown feature to minimize power consumption.

Digital Potentiometers Feature Summary

• 256-position resolution with 10 kΩ nominal resistance and 30 ppm/°C temperature coefficient
• I²C-compatible 2-wire serial interface with readback capability and up to four addressable devices per bus
• Internal power-on midscale preset and active-low shutdown pin for low-power operation
• Two extra programmable push-pull logic outputs (O1, O2) for driving digital loads

Digital Potentiometers Applications

• Multimedia, video, and audio signal control
• Instrumentation gain and offset adjustment
• Mechanical potentiometer replacement in compact designs
• Programmable voltage-to-current conversion circuits
• Line impedance matching applications

Digital Potentiometers Procurement Notes

Verify the specific package variant required, as the AD5241 series is available in 14-lead SOIC and TSSOP packages. Confirm that the system design accommodates the extended temperature range of −40°C to +105°C. Ensure the I²C bus voltage levels are compatible with the device's logic thresholds at the selected supply voltage. Check for ESD sensitivity precautions during handling and assembly.

Digital Potentiometers Selection Notes

Select the AD5241BR10 when a single-channel variable resistor with 10 kΩ end-to-end resistance is needed. Choose this part over the AD5242 if only one channel is required. Consider the 100 kΩ or 1 MΩ variants if higher resistance values are necessary for lower current applications. Verify that the 8-bit resolution meets the precision requirements for the intended analog adjustment task.

Digital Potentiometers Part Context

The AD5241BR10 belongs to the AD5241/AD5242 family of I²C-compatible digital potentiometers. It serves as the single-channel counterpart to the dual-channel AD5242. Both devices share identical electrical characteristics, interface protocols, and packaging options, differing primarily in the number of integrated variable resistors. This component replaces traditional mechanical potentiometers in space-constrained PCB layouts.
