AD5114BCPZ80-1-RL7

Overview

The AD5114BCPZ80-1-RL7 is a single-channel, nonvolatile digital potentiometer featuring 32 adjustment positions and an I2C-compatible interface. It offers a nominal resistance of 80 kΩ with a maximum tolerance error of ±8%. The device operates on a 2.3 V to 5.5 V analog supply and supports logic levels from 1.8 V to 5.5 V. Key specifications include a wiper current of ±6 mA, a rheostat mode temperature coefficient of 35 ppm/°C, and low power consumption of 2.5 µA max at 2.7 V and 125°C. 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 and 1 million write cycle endurance.
• I2C serial interface allows control and readback of the RDAC register and EEPROM content.
• Low wiper resistance (typical 45 Ω) minimizes resistance in extreme array positions.
• Wide operating temperature range from −40°C to +125°C.

Applications

• Mechanical potentiometer replacement
• Portable electronics level adjustment
• Audio volume control
• Low resolution DAC
• LCD panel brightness and contrast control

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel configuration. Ensure compatibility with the target system's I2C bus voltage levels and address requirements before procurement.

Selection Notes

Select this component when 32-position resolution is sufficient for the application. Verify that the 80 kΩ resistance value aligns with the circuit's impedance requirements. Confirm that the I2C interface speed (Standard or Fast mode) meets the system timing constraints.

Part Context

This part belongs to the AD511x family of single-channel digital potentiometers. It shares the same 8-lead LFCSP package and core architecture as the AD5110 (128-position) and AD5112 (64-position), differing primarily in the number of available tap positions.

Replacement Considerations

Direct functional replacements within the same family include the AD5110BCPZ80-1-RL7 and AD5112BCPZ80-1-RL7. These alternatives offer higher resolution (128 and 64 positions, respectively) while maintaining identical pinouts and electrical characteristics.
