AD5112BCPZ5-500R7

Overview

The AD5112BCPZ5-500R7 is a single-channel, nonvolatile digital potentiometer featuring 64 tap positions and an I²C interface. It offers a nominal resistance of 5 kΩ with ±8% tolerance and a temperature coefficient of 35 ppm/°C. The device operates on a 2.3 V to 5.5 V analog supply and supports 1.8 V logic levels. Key electrical parameters include a maximum wiper current of ±6 mA, a bandwidth of 4 MHz at the 5 kΩ setting, and low power consumption of 2.5 µA max at 2.7 V. It utilizes EEPROM for data retention, ensuring settings persist across power cycles.

Feature Summary

• Nonvolatile memory with 50-year typical data retention at 125°C
• I²C-compatible serial interface for control and readback
• Low wiper resistance (typical 45 Ω) in extreme positions
• High bandwidth of 4 MHz for the 5 kΩ option

Applications

• Mechanical potentiometer replacement
• Portable electronics level adjustment
• Audio volume control
• Low resolution DAC applications
• Sensor calibration

Procurement Notes

Verify the specific suffix '500R7' against official Analog Devices documentation to confirm packaging details such as reel or cut tape specifications. Ensure compatibility with the required I²C bus speed and voltage levels before procurement.

Selection Notes

Select this component for applications requiring precise, programmable resistance with nonvolatile storage. The 5 kΩ value provides a 4 MHz bandwidth, suitable for higher frequency signal conditioning. Verify that the ±8% resistor tolerance meets the system accuracy requirements.

Part Context

This part belongs to the AD5112 family of single-channel digital potentiometers. It shares architectural similarities with the AD5110 and AD5114 but is distinguished by its 64-position resolution and I²C interface, differentiating it from up/down or push-button controlled variants.

Replacement Considerations

Direct replacements within the same family include other AD5112 variants with different resistance values (e.g., 10 kΩ or 80 kΩ). Cross-family substitution requires careful evaluation of pinout compatibility and interface protocol differences.
