AD5116BCPZ5-500R7

Overview

The AD5116BCPZ5-500R7 is a single-channel, nonvolatile digital potentiometer featuring 64 tap positions and a nominal resistance of 5 kΩ. It utilizes a push-button interface for manual control and includes an adaptive debouncer. The device operates on a single supply voltage ranging from 2.3 V to 5.5 V with a maximum wiper current of ±6 mA. Key electrical specifications include a resistor tolerance of ±8%, a temperature coefficient of 35 ppm/°C, and a bandwidth of 4 MHz at the 5 kΩ setting. It is housed in an 8-lead LFCSP package.

Feature Summary

• Nonvolatile EEPROM memory retains wiper position across power cycles
• Built-in adaptive debouncer for direct push-button interface
• Low wiper resistance feature (45 Ω typical at bottom scale)
• Wide operating temperature range from -40°C to +125°C

Applications

• Mechanical potentiometer replacement
• Audio volume control
• LCD panel brightness and contrast adjustment
• Sensor calibration
• Programmable filters and time constants

Procurement Notes

Verify the specific suffix '5' corresponds to the 5 kΩ resistance value as indicated by the model designation. Confirm the '500R7' suffix matches the reel packaging format required for the assembly process. Cross-reference the manufacturer part number with official Analog Devices documentation to ensure component authenticity and revision status.

Selection Notes

Select this component when a simple manual control interface without external microcontrollers is required. The 5 kΩ resistance value is suitable for applications requiring moderate current handling up to ±6 mA. Ensure the application voltage stays within the 2.3 V to 5.5 V range and that the PCB layout accommodates the 2 mm × 2 mm LFCSP package dimensions.

Part Context

This part belongs to the AD5116 family of nonvolatile digital potentiometers. It is distinguished from other models like the AD5112 or AD5113 by its push-button interface rather than I2C or up/down serial interfaces. The family shares common features such as nonvolatile storage and low power consumption but varies in resolution and communication protocols.

Replacement Considerations

Direct replacements within the same interface type are limited. The AD5116 is unique in the series for using push buttons. Other models like AD5112 or AD5113 require different control logic. Verify if the system can accommodate alternative interfaces if exact pin-for-pin substitutes are unavailable.
