ISL60002DIH311Z

Overview

The ISL60002DIH311Z is a precision low-power FGA voltage reference IC manufactured by Intersil, now part of Renesas Electronics. It provides a fixed output voltage of 1.2 V with an initial accuracy of 0.42%. The device operates within a maximum series input voltage of 6.5 V and supports a maximum shunt current of 7 mA. It features a temperature coefficient of 20 ppm/°C and functions reliably across an operating temperature range from -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount case, it is designed for applications requiring stable voltage references in space-constrained environments.

Feature Summary

• Delivers precise voltage regulation with low power consumption characteristics suitable for battery-operated systems.
• Utilizes FGA technology to ensure long-term stability and minimal drift over time and temperature variations.
• Offers high initial accuracy to maintain signal integrity in sensitive analog circuits without frequent calibration.

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-powered measurement devices
• Data acquisition systems needing accurate analog-to-digital conversion references

Procurement Notes

Verify the manufacturer designation as Intersil or Renesas Electronics depending on the production era. Confirm the package type is SOT-23-3 and the output voltage is strictly 1.2 V. Ensure the suffix matches the specific reel or cut tape configuration required for your assembly process. Check RoHS compliance status against the latest datasheet revision before ordering.

Selection Notes

Select this component when a 1.2 V reference is needed with moderate accuracy (0.42%) and low quiescent current. It is suitable for designs where space is limited due to the small SOT-23-3 footprint. Consider the 20 ppm/°C temperature coefficient if the operating environment experiences significant thermal fluctuations. Compare against higher accuracy variants if tighter tolerances are required for your specific application.

Part Context

This part belongs to the ISL60002 series of precision voltage references. The series includes various output voltages and accuracy grades, all sharing similar low-power architectures. The DIH311 suffix specifically denotes the 1.2 V output variant with 0.42% initial accuracy. This family is widely used in industrial and consumer electronics where reliable voltage referencing is critical for system performance.

Replacement Considerations

Direct substitutes include other parts from the ISL60002 series with identical pinouts and similar electrical characteristics. Verify that any replacement maintains the same 1.2 V output and SOT-23-3 package. Cross-reference with Renesas' current portfolio for updated part numbers if Intersil branding is no longer supported in new designs.
