Overview
The ISL21007DFB825Z-TK is a precision series voltage reference from the Intersil family, providing a fixed output of 2.5 V. It operates within an input voltage range of 2.7 V to 5.5 V and features a maximum initial accuracy of 0.16%. The device exhibits low noise characteristics, specified at 4.5 µVp-p for the 0.1 Hz to 10 Hz frequency band. It maintains a temperature coefficient of 10 ppm/°C and draws a maximum operating current of 150 µA. The component is housed in an 8-SOIC package.
Feature Summary
- Provides stable 2.5 V reference with high initial accuracy
- Features very low noise performance for sensitive applications
- Operates with low quiescent current consumption
Applications
- Precision analog-to-digital converter (ADC) references
- Digital-to-analog converter (DAC) voltage sources
- High-resolution measurement instrumentation
Procurement Notes
Verify the specific suffix 'TK' against the manufacturer's official documentation to confirm packaging details such as reel or cut tape specifications. Ensure the part number matches the exact electrical parameters required for your design, particularly the 2.5 V output and 8-SOIC package constraints. Cross-reference with Renesas legacy product lists to confirm current availability status.
Selection Notes
Select this component when a low-noise, low-power series reference is required for 2.5 V applications. The 10 ppm/°C temperature coefficient suits environments with moderate thermal variations. Consider the 150 µA max current draw for battery-powered systems where power efficiency is critical alongside precision requirements.
Part Context
This part belongs to the ISL21007 series of precision voltage references manufactured by Intersil, now integrated into Renesas Electronics. The series is designed for high-performance analog circuits requiring stable voltage sources with minimal drift and noise.
Replacement Considerations
Consult Renesas Product Legacy Documents for officially confirmed substitute part numbers. Verify pin compatibility and electrical parameter equivalence before substitution.
