AD5112BCPZ80-1-RL7

Overview

The AD5112BCPZ80-1-RL7 is a single-channel, nonvolatile digital potentiometer featuring 64 tap positions and an I²C interface. It offers a nominal resistance of 80 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 ±1.5 mA for the 80 kΩ variant, low power consumption (2.5 µA max at 2.7 V), and EEPROM data retention of 50 years. It is housed in an 8-lead LFCSP package.

Feature Summary

• Nonvolatile memory with 50-year typical data retention and 1 million write cycles
• I²C-compatible serial interface for setting and reading wiper position
• Low wiper resistance (typical 70 Ω) and ±8% resistor tolerance
• 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 suffix '-1' against the manufacturer's official ordering guide to confirm if it denotes a specific tape-and-reel quantity or packaging variation. Ensure compatibility with standard I²C bus pull-up requirements and check for moisture sensitivity classification prior to surface-mount assembly.

Selection Notes

Select this component for applications requiring precise, programmable resistance without mechanical wear. The 80 kΩ value suits lower-current signal paths where the ±1.5 mA continuous terminal current limit is sufficient. Consider the 5 kΩ or 10 kΩ variants if higher current handling or wider bandwidth is required.

Part Context

This part belongs to the AD5112 family of single-channel digital potentiometers. It shares architectural similarities with the AD5110 (128-position) and AD5114 (32-position) but is distinct in its 64-position resolution. The 'BCPZ' designation indicates the 8-lead LFCSP package and lead-free construction.

Replacement Considerations

Direct pin-to-pin replacements within the same family include the AD5112BCPZ5-RL7 (5 kΩ) and AD5112BCPZ10-RL7 (10 kΩ). Verify that the alternative resistance value meets the circuit's current and voltage divider requirements.
