ISL21007DFB825ZS2705

Overview

The ISL21007DFB825ZS2705 is a series voltage reference IC manufactured by Renesas Electronics Corporation. It provides a fixed output voltage of 2.5V with a tolerance of ±2%. The device operates within an input voltage range of 2.7V to 5.5V and supports an output current of up to 7 mA. It is housed in an 8-SOIC package (0.154 inch width) designed for surface mount installation.

Feature Summary

• Provides a stable fixed 2.5V series voltage reference output
• Operates with a wide input voltage range from 2.7V to 5.5V
• Delivers up to 7 mA of load current capability
• Utilizes an 8-SOIC surface-mount package for board integration

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Battery-powered instrumentation requiring stable bias voltages
• Data acquisition systems needing reliable reference potentials

Procurement Notes

Verify the exact suffix S2705 against official Renesas documentation to confirm packaging and tape-and-reel specifications. Confirm RoHS3 compliance status for your region. Check for obsolescence notices or PCNs as this component may have limited availability. Ensure the 8-SOIC footprint matches your PCB design requirements before ordering.

Selection Notes

Select this part when a 2.5V reference is required with moderate accuracy (±2%). Consider the ISL21007CFB830Z if higher precision (±0.08%) and lower noise are needed, despite its different output voltage. Evaluate the input voltage range compatibility with your system power supply. The 7 mA output current is suitable for driving ADCs/DACs directly without additional buffering in many cases.

Part Context

This component belongs to the ISL21007 family of high-precision voltage references from Renesas. The family includes variants with different output voltages and tolerances, such as the 3V/±0.08% ISL21007CFB830Z. These devices share similar internal architectures optimized for low noise and stability, serving as critical reference elements in mixed-signal circuits.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Designers should consult Renesas for qualified alternatives or verify cross-reference data through official distributor channels.
