AD5114BCPZ10-500R7

Overview

The AD5114BCPZ10-500R7 is a single-channel, nonvolatile digital potentiometer featuring 32 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 1.8 V logic levels. Key specifications include a maximum wiper current of ±6 mA, low power consumption (2.5 µA max at 2.7 V), and EEPROM storage for wiper settings. It is housed in a compact 2 mm × 2 mm × 0.55 mm 8-lead LFCSP package.

Feature Summary

• Nonvolatile memory retains wiper position after power loss with 50-year typical retention.
• I²C-compatible serial interface allows control and readback of RDAC register and EEPROM.
• Low wiper resistance minimizes error in extreme positions (typical 45 Ω).
• High bandwidth of 2 MHz at 10 kΩ facilitates open-loop applications.

Applications

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

Procurement Notes

Verify the specific suffix '500R7' against official documentation to confirm packaging details such as reel size or tape width. Confirm that the 'B' grade indicates the specified ±8% resistor tolerance. Ensure the ordering code matches the exact resistance value and interface requirements for the target design.

Selection Notes

Select this component when 32-position resolution is sufficient for the application. Verify that the required wiper current does not exceed ±6 mA. Ensure the system voltage falls within the 2.3 V to 5.5 V range. Consider the 2 MHz bandwidth if high-frequency signal processing is involved. Check compatibility with the available I²C bus speed (Standard or Fast mode).

Part Context

This part belongs to the AD511x family of nonvolatile digital potentiometers from Analog Devices. It shares architectural similarities with the AD5110 (128-position) and AD5112 (64-position) but provides fewer taps for simpler control loops. All variants in this series utilize the same 8-lead LFCSP package and I²C interface protocol.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material. When evaluating alternatives, ensure the replacement maintains the 10 kΩ resistance, 32-position resolution, I²C interface, and nonvolatile memory capability. Verify pinout compatibility with the 8-lead LFCSP package.
