Procurement Notes

Verify component authenticity through authorized channels as the device is sensitive to electrostatic discharge. Confirm package type and marking codes match official documentation. Check RoHS compliance status if required by specific manufacturing standards. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity.

Selection Notes

Select this model when precise 2.5V reference is needed with strict accuracy requirements. Consider the 5ppm/°C temperature coefficient for thermal stability needs. Evaluate the 400nA supply current against system power budgets. Verify compatibility with 2.7V to 5.5V input ranges. Assess packaging constraints for the 8-lead SOIC form factor.

Part Context

Part of the ISL60007 FGA™ family designed for high-resolution data conversion systems. Combines low power with high precision, eliminating trade-offs between accuracy and energy efficiency. Suitable for applications requiring stable references in portable or battery-operated environments.

Replacement Considerations

ISL60007BIB825 offers similar specifications but with a tighter 3ppm/°C temperature coefficient. ISL60007DIB825 provides lower initial accuracy at ±1.0mV but maintains the same package and basic electrical characteristics. Verify pinout and thermal performance before substitution.

FAQ

What is the typical turn-on time for the ISL60007CIB825?

Normal turn-on time is typically 4ms, though it can last up to about 6ms due to variations in supply current down to 250nA.

How does the device handle output noise reduction?

Noise in the 10kHz to 1MHz band can be reduced using a 0.001µF capacitor. For full bandwidth reduction, a network with a 0.01µF capacitor and a 2kΩ resistor in series with a 10µF capacitor is recommended.
