AD5116BCPZ80-500R7

Overview

The AD5116BCPZ80-500R7 is a single-channel, nonvolatile digital potentiometer featuring 64 positions and a nominal resistance of 80 kΩ. It utilizes a push-button interface with an adaptive debouncer for manual control. Key electrical specifications include ±8% maximum resistor tolerance, a rheostat mode temperature coefficient of 35 ppm/°C, and a bandwidth of 200 kHz at the 80 kΩ setting. The device operates on a 2.3 V to 5.5 V supply, consumes a maximum of 2.5 µA at 2.7 V, and supports up to ±1.5 mA wiper current. It includes EEPROM storage for power-on restoration and functions within an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Push-button interface with built-in adaptive debouncer
• Nonvolatile EEPROM memory with <50 μs power-on restore time
• ±8% nominal resistor tolerance and 35 ppm/°C temperature coefficient
• 8-lead LFCSP package (2 mm × 2 mm)

Applications

• Mechanical potentiometer replacement
• Audio volume control
• LCD panel brightness and contrast control
• Sensor calibration

Procurement Notes

Verify the ordering suffix '80' corresponds to the 80 kΩ resistance value and '500R7' indicates the reel packaging format. Confirm the 'BCPZ' suffix denotes the lead-free LFCSP package variant. Ensure the source document explicitly links these suffixes to the specific electrical parameters listed in the datasheet table.

Selection Notes

Select this component when a 64-position adjustment is required without serial communication interfaces. The 80 kΩ resistance option provides a 200 kHz bandwidth, suitable for lower-frequency signal conditioning. Verify that the application current does not exceed ±1.5 mA continuous for the 80 kΩ version. The push-button interface simplifies hardware design by eliminating I2C or SPI controller requirements.

Part Context

The AD5116 belongs to the NVM ±8% Resistance Tolerance family, which also includes models with I2C (AD5110, AD5112) and up/down counter (AD5111, AD5113) interfaces. Unlike the AD5112, which shares the 64-position count but uses I2C, the AD5116 relies on tactile switches. This distinguishes it from higher-resolution variants like the AD5110/AD5111 which offer 128 positions.

Replacement Considerations
