AD5110BCPZ10-500R7

Overview

The AD5110BCPZ10-500R7 is a single-channel, nonvolatile digital potentiometer featuring 128 adjustment positions and an I²C-compatible interface. It offers a nominal resistance of 10 kΩ with a maximum tolerance error of ±8%. The device operates on a single analog supply voltage ranging from 2.3 V to 5.5 V and supports logic supplies from 1.8 V to 5.5 V. Key electrical parameters include a wiper current of ±6 mA, a rheostat mode temperature coefficient of 35 ppm/°C, and a power-on EEPROM refresh time of less than 50 μs. It is housed in a thin, 2 mm × 2 mm × 0.55 mm 8-lead LFCSP package.

Feature Summary

• Nonvolatile memory with 1 million write cycles and 50-year typical data retention at 125°C
• I²C-compatible serial interface for wiper setting and EEPROM readback
• Low wiper resistance (typical 45 Ω) and guaranteed ±8% resistor tolerance
• Wide operating temperature range from −40°C to +125°C

Applications

• Mechanical potentiometer replacement
• Portable electronics level adjustment
• Audio volume control
• LCD panel brightness and contrast control
• Sensor calibration

Procurement Notes

Verify the specific suffix '500R7' against official Analog Devices documentation to confirm packaging details such as reel size or tape-and-reel specifications. Ensure compatibility with the required I²C bus speed (Standard or Fast mode) and check that the logic supply voltage meets the minimum 1.8 V requirement for proper interface operation.

Selection Notes

Select this component when a nonvolatile solution is required to retain wiper settings after power loss. The 10 kΩ resistance value and 128-position resolution are suitable for applications requiring moderate precision. Ensure the application current does not exceed the ±6 mA continuous limit for the 10 kΩ version and verify that the PCB layout accommodates the 8-lead LFCSP footprint.

Part Context

This part belongs to the AD5110/AD5112/AD5114 family of single-channel digital potentiometers. The AD5110 specifically provides 128 positions, distinguishing it from the 64-position AD5112 and 32-position AD5114 variants within the same series. All members share similar electrical characteristics and package options but differ in resolution.

Replacement Considerations

Direct substitutes within the same family include the AD5110BCPZ80-1-RL7 (80 kΩ variant) if higher resistance is acceptable. For different resolutions, consider the AD5112 series (64 positions) or AD5114 series (32 positions). Verify that any replacement maintains the I²C interface and nonvolatile memory requirements.
