AD5111BCPZ80-RL7

Overview

The AD5111BCPZ80-RL7 is a single-channel, nonvolatile digital potentiometer featuring an 80 kΩ resistance value with 32 adjustment positions. It operates on a supply voltage ranging from 2.3 V to 5.5 V and utilizes an I²C-compatible serial interface for data transfer. The device incorporates an onboard EEPROM that retains the wiper setting upon power loss, ensuring immediate operational readiness. Key electrical characteristics include a maximum resistor tolerance error of ±8% and a rheostat mode temperature coefficient of 35 ppm/°C. The component supports a maximum clock frequency of 50 MHz and provides up to ±1.5 mA current density through the A, W, and B terminals.

Feature Summary

• Nonvolatile memory with 1 million write cycles and 50-year typical data retention at 125°C
• Guaranteed low resistor tolerance error of ±8% maximum
• Wide bandwidth capability suitable for open-loop applications
• Power-on EEPROM refresh time less than 50 μs

Applications

• Mechanical potentiometer replacement
• Portable electronics level adjustment
• Audio volume control
• LCD panel brightness and contrast control
• Sensor calibration

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and reel quantity specifications. Ensure compatibility with system voltage levels and interface protocols before integration. Confirm environmental operating ranges align with application requirements.

Selection Notes

Select this model for applications requiring precise resistance adjustment without mechanical wear. The 80 kΩ variant is suitable for higher impedance circuits where lower current handling is acceptable. Consider the ±8% tolerance when designing precision analog signal paths or feedback networks.

Part Context

This component belongs to the AD5111/AD5113/AD5115 family of digital potentiometers. The AD5111 specifically offers 32-position adjustment, distinguishing it from the 64-position AD5113 and 128-position AD5115 variants within the same product line.

Replacement Considerations

Direct substitutes include other models within the AD511x series such as the AD5113 or AD5115, provided the position count meets design needs. Verify pinout compatibility and electrical parameters like wiper current limits when considering alternative manufacturers.
