Overview
The AD5141WBCPZ10-RL7 is a single-channel, nonvolatile digital potentiometer featuring 256 tap positions and a 10 kΩ resistance value. It supports both SPI and I2C interfaces via the DIS pin. Key electrical parameters include an 8% maximum resistor tolerance, a 35 ppm/°C temperature coefficient, and a 3 MHz bandwidth. The device operates on a single supply of 2.3 V to 5.5 V or dual supplies of ±2.25 V to ±2.75 V, with a logic supply range of 1.8 V to 5.5 V. It provides up to ±6 mA wiper current and includes EEPROM for data retention.
Feature Summary
- Nonvolatile memory with 256 positions and 10 kΩ nominal resistance
- Dual interface support: SPI (DIS=0) and I2C (DIS=1)
- Wide operating temperature range from -40°C to +125°C
- Linear gain setting mode via INDEP pin for accurate resistor matching
Applications
- Portable electronics level adjustment
- LCD panel brightness and contrast controls
- Programmable filters, delays, and time constants
- Programmable power supplies
Procurement Notes
Verify the 'WB' suffix against official documentation to confirm automotive qualification status, as standard datasheets may list generic variants. Confirm package dimensions for the 16-lead LFCSP (3 mm × 3 mm) during layout. Ensure ESD precautions are taken due to sensitivity ratings.
Selection Notes
Select this model for applications requiring high resolution (8-bit) and nonvolatile storage in a compact footprint. Choose between SPI and I2C based on system bus availability by configuring the DIS pin. Ensure the 10 kΩ resistance and ±6 mA current limits align with the target circuit requirements.
Part Context
This component belongs to the AD5121/AD5141 family of single-channel digital potentiometers. The AD5141 variant specifically offers 256 positions compared to the 128 positions of the AD5121. Both share similar electrical characteristics and packaging options within the Analog Devices portfolio.
Replacement Considerations
The AD5141BCPZ10-RL7 is a direct functional substitute within the same family, differing primarily in the absence of the 'W' automotive qualification suffix. Verify pin compatibility and electrical specifications before substitution.
