Overview
The AD5110BCPZ80-500R7 is a single-channel, nonvolatile digital potentiometer featuring 128 adjustment positions and an 80 kΩ nominal resistance. It utilizes an I²C-compatible interface for wiper setting and EEPROM readback. The device operates on a single analog supply of 2.3 V to 5.5 V and a logic supply of 1.8 V to 5.5 V. Key electrical characteristics include a maximum resistor tolerance error of ±8%, a rheostat mode temperature coefficient of 35 ppm/°C, and a typical bandwidth of 200 kHz at the 80 kΩ setting. It supports up to ±6 mA continuous current density and offers 50-year data retention with 1 million write cycles.
Feature Summary
- Nonvolatile memory stores wiper settings and resistor tolerance (0.1% accuracy) for power-on restoration.
- I²C-compatible serial interface allows control and readback of RDAC register and EEPROM content.
- Low wiper resistance of 45 Ω typical in extremes minimizes array resistance errors.
- Operates over extended industrial temperature range from −40°C to +125°C.
Applications
- Mechanical potentiometer replacement
- Portable electronics level adjustment
- Audio volume control
- LCD panel brightness and contrast control
- Sensor calibration
Procurement Notes
Verify the specific suffix '500R7' against official Analog Devices documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure the ordering code matches the required 80 kΩ resistance value and LFCSP package type. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity.
Selection Notes
Select this component when 128-position resolution and nonvolatile storage are required for an 80 kΩ variable resistor. The I²C interface is suitable for systems needing minimal pin count. Consider the 200 kHz bandwidth limit for high-frequency applications; lower resistance options like the 5 kΩ variant offer higher bandwidth if signal speed is critical.
Part Context
This part belongs to the AD5110 family, which provides nonvolatile solutions for 128-position adjustment. It shares features with the AD5112 (64-position) and AD5114 (32-position) variants but distinguishes itself with higher resolution. The BC designation typically indicates the temperature grade and package style within the Analog Devices portfolio.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material.
FAQ
What is the power-on EEPROM refresh time?
The power-on EEPROM refresh time is less than 50 μs.
How does the device handle resistor tolerance?
Resistor tolerance is stored within the EEPROM, providing an end-to-end tolerance accuracy of 0.1%.
What is the maximum continuous current for the 80 kΩ version?
The maximum continuous current for the 80 kΩ version is ±1.5 mA.
