AD5116BCPZ10-RL7

Overview

The AD5116BCPZ10-RL7 is a single-channel, nonvolatile digital potentiometer featuring 64 tap positions and a nominal resistance of 10 kΩ. It utilizes a push-button interface with an adaptive debouncer for manual control. The device operates on a 2.3 V to 5.5 V supply, drawing a maximum of 3.5 µA at 5 V. Key electrical characteristics include ±8% resistor tolerance, a rheostat mode temperature coefficient of 35 ppm/°C, and a wiper current capacity of ±6 mA. It incorporates EEPROM memory for data retention, ensuring the last wiper position is restored upon power-up.

Feature Summary

• Single-channel digital potentiometer with 64 positions and 10 kΩ nominal resistance
• Push-button interface with built-in adaptive debouncer for manual adjustment
• Nonvolatile EEPROM storage retains wiper position across power cycles
• Low power consumption: 3.5 µA max at 5 V; 2.5 µA max at 2.7 V
• ±8% resistor tolerance and 35 ppm/°C temperature coefficient

Applications

• Mechanical potentiometer replacement in industrial equipment
• Audio volume control and level adjustment in portable electronics
• LCD panel brightness and contrast control
• Programmable filters, delays, and time constants
• Sensor calibration circuits

Procurement Notes

Verify the specific suffix RL7 corresponds to reel packaging when sourcing. Confirm the B grade indicates ±8% resistor tolerance. Ensure the C grade denotes the extended industrial temperature range of −40°C to +125°C. Cross-reference the 10 kΩ resistance value with the exact part number variant required for the design.

Selection Notes

Select this component for applications requiring manual user adjustment via tactile switches without external microcontrollers. The 10 kΩ option provides a balance between bandwidth (2 MHz) and noise performance. Consider the LFCSP-8 package dimensions (2 mm × 2 mm) for space-constrained PCB layouts. Ensure the application voltage stays within the 2.3 V to 5.5 V range to maintain specified electrical characteristics.

Part Context

This part belongs to the AD5116 family of nonvolatile digital potentiometers. It shares the same core architecture and interface as other variants in the series but is distinguished by its 10 kΩ resistance value and push-button control method. Other family members may offer different resistances (5 kΩ, 80 kΩ) or interfaces like I2C.

Replacement Considerations

Direct replacements within the Analog Devices portfolio include AD5116BCPZ5-RL7 (5 kΩ) and AD5116BCPZ80-RL7 (80 kΩ) for identical functionality with different resistance values. For interface changes, consider the AD5112 (I2C) or AD5113 (Up/down) if push-button control is not required.
