AD5111BCPZ10-RL7

Overview

The AD5111BCPZ10-RL7 is a single-channel, nonvolatile digital potentiometer featuring 128 adjustment positions. It operates within a supply voltage range of 2.3 V to 5.5 V and utilizes an I²C-compatible serial interface with CLK, CS, and U/D pins for data transmission. The device incorporates an internal EEPROM that refreshes in less than 50 μs upon power-on, ensuring immediate wiper position retention. It supports maximum continuous currents of ±6 mA for the 5 kΩ and 10 kΩ resistance options, with a wide bandwidth of 4 MHz for the 5 kΩ variant.

Feature Summary

• Nonvolatile memory with 1 million write cycles and 50-year typical data retention at 125°C
• Nominal resistor tolerance error of ±8% maximum
• Low power consumption: 2.5 µA max @ 2.7 V and 125°C
• Thin 2 mm × 2 mm × 0.55 mm 8-lead LFCSP package

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 'BCPZ10-RL7' against official Analog Devices documentation to confirm the exact resistance value (10 kΩ) and tape-and-reel packaging configuration. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS structure.

Selection Notes

Select this component for applications requiring precise, nonvolatile resistance adjustment without external memory. The 10 kΩ option offers a 4 MHz bandwidth suitable for high-speed signal conditioning. Verify that the system clock does not exceed the 50 MHz limit and that current requirements stay within the ±6 mA continuous rating for low-resistance variants.

Part Context

This part belongs to the AD5111/AD5113/AD5115 family of digital potentiometers. The AD5111 specifically provides 128 positions, distinguishing it from the 64-position AD5113 and 32-position AD5115. All members share similar electrical characteristics and pinouts but differ in resolution and total resistance steps.

Replacement Considerations

Direct replacements include other AD5111 variants with different resistance values or packages. Cross-model substitutes like AD5113 or AD5115 offer fewer positions but maintain compatibility. Verify pinout and command set alignment before substitution.
