Overview
The AD5144ABRUZ10-RL7 is a quad-channel, nonvolatile digital potentiometer featuring 256 tap positions and an I2C interface. It offers a nominal resistance of 10 kΩ with ±8% tolerance and a temperature coefficient of 35 ppm/°C. The device supports single or dual supply operation (VDD: 2.3 V to 5.5 V) and includes independent logic supply (VLOGIC: 1.8 V to 5.5 V). Key electrical parameters include a maximum wiper current of ±6 mA, 3 MHz bandwidth, and fast startup time under 75 µs. It is housed in a 20-lead TSSOP package.
Feature Summary
- Quad-channel architecture with 256-position resolution and nonvolatile memory for wiper settings.
- I2C-compatible serial interface for setting wiper values and reading back EEPROM contents.
- Wide operating voltage range supporting single (2.3 V to 5.5 V) and dual-supply configurations.
- High bandwidth (3 MHz) and low total harmonic distortion suitable for AC signal applications.
Applications
- Portable electronics level adjustment
- LCD panel brightness and contrast controls
- Programmable filters, delays, and time constants
- Programmable power supplies
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm interface type and package details. Ensure compatibility with system voltage levels and communication protocols before integration. Check for RoHS compliance status as indicated in the datasheet specifications.
Selection Notes
Select this component for applications requiring precise, nonvolatile resistance adjustment across four independent channels. The 10 kΩ value and ±8% tolerance are suitable for open-loop control and tolerance matching tasks. Consider the 20-lead TSSOP package for space-constrained PCB layouts requiring surface-mount installation.
Part Context
This part belongs to the AD5124/AD5144/AD5144A family of digital potentiometers. The 'A' designation indicates an I2C-only interface variant, distinguishing it from SPI/I2C compatible models like the AD5144. The 'RUZ' suffix denotes the 20-lead TSSOP package, while '10' specifies the 10 kΩ end-to-end resistance.
Replacement Considerations
For direct functional replacement within the same family, consider the AD5144BRUZ10 for SPI/I2C compatibility or the AD5144ABRUZ100 for 100 kΩ resistance options. Verify pinout compatibility between TSSOP variants when substituting.
