AD5124BCPZ10-RL7

Overview

The AD5124BCPZ10-RL7 is a quad-channel, nonvolatile digital potentiometer featuring 128 positions and an SPI interface. It offers 10 kΩ nominal resistance with ±8% tolerance and supports single or dual supply operation (VDD: 2.3 V to 5.5 V; VLOGIC: 1.8 V to 5.5 V). The device provides up to ±6 mA wiper current, 3 MHz bandwidth, and fast startup under 75 µs. Packaged in a 24-lead LFCSP, it operates from −40°C to +125°C.

Feature Summary

• Quad-channel architecture with 128-position resolution
• Nonvolatile EEPROM storage for data retention
• SPI-compatible serial interface
• ±6 mA maximum wiper current capability

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 suffix '10' indicates the 10 kΩ resistor option and 'RL7' denotes the reel packaging configuration. Confirm that the B grade meets the required temperature range specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when four independent digital potentiometers are required within a single package. Ensure the system logic voltage falls within the 1.8 V to 5.5 V range. Verify that the 10 kΩ resistance value aligns with the circuit's impedance requirements and that SPI communication protocols are supported by the host controller.

Part Context

This part belongs to the AD5124/AD5144 family of nonvolatile digital potentiometers. The AD5124 variant specifically provides 128 tap positions per channel, distinguishing it from the 256-position AD5144 series. The LFCSP package allows for compact board layouts in space-constrained designs.

Replacement Considerations

The AD5124BRUZ100-RL7 serves as a parameter-equivalent alternative utilizing a TSSOP package instead of LFCSP. Both devices share identical electrical characteristics and pinout configurations for the SPI interface.
