AD5112BCPZ10-1-RL7

Overview

The AD5112BCPZ10-1-RL7 is a single-channel, nonvolatile digital potentiometer featuring 64 tap positions and an I²C interface. It offers a nominal resistance of 10 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 logic levels from 1.8 V to VDD. Key specifications include a maximum wiper current of ±6 mA, a bandwidth of 2 MHz at the 10 kΩ setting, and EEPROM storage for wiper position data retention exceeding 50 years.

Feature Summary

• Nonvolatile memory retains wiper settings across power cycles with >50-year retention.
• I²C-compatible serial interface allows control and readback of RDAC register and EEPROM content.
• Low wiper resistance (typical 45 Ω) minimizes error in extreme positions.
• Operates over extended industrial temperature range (-40°C to +125°C).

Applications

• Mechanical potentiometer replacement
• Portable electronics level adjustment
• Audio volume control
• Sensor calibration

Procurement Notes

Verify the specific ordering suffix '-1' against official Analog Devices documentation to confirm if it denotes a specific tape-and-reel quantity or packaging variant, as standard datasheets may list base part numbers without this suffix. Confirm availability through authorized distributors.

Selection Notes

Select this component for applications requiring precise, digitally adjustable resistance with persistent settings. Ensure the 10 kΩ resistance value matches the circuit requirements and that the I²C bus speed (Standard or Fast mode) is compatible with the system controller. Verify voltage levels for both analog supply and logic inputs.

Part Context

This part belongs to the AD5112 family within the AD5110/AD5112/AD5114 series. These devices are designed as low-power, nonvolatile alternatives to mechanical potentiometers, offering guaranteed resistor tolerance errors and high bandwidth for open-loop applications.

Replacement Considerations

Direct replacements within the same family include AD5112BCPZ5-RL7 (5 kΩ) and AD5112BCPZ80-1-RL7 (80 kΩ), provided the resistance value difference is acceptable for the application.
