ISL60002CAH333Z

Overview

The ISL60002CAH333Z is a precision voltage reference from the Renesas Intersil ISL60002 family, utilizing proprietary Floating Gate Analog (FGA) technology. It provides a fixed output voltage of 3.3V with an initial accuracy of ±0.08% and a temperature coefficient of 20 ppm/°C. The device operates within an input voltage range of 3.5V to 5.5V and supports a maximum sink current of 7mA. It functions reliably across an extended industrial temperature range from -40°C to +105°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Utilizes proprietary Floating Gate Analog (FGA) technology for high precision and stability
• Features ultra-low supply current consumption for power-efficient designs
• Provides guaranteed initial accuracy and low temperature drift characteristics
• Includes robust ESD protection on bus pins

Applications

• High-resolution data acquisition systems
• Portable battery-powered instrumentation
• Precision analog-to-digital converter (ADC) references
• Medical diagnostic equipment requiring stable voltage sources

Procurement Notes

Verify the specific suffix 'Z' indicates lead-free (RoHS compliant) construction as per manufacturer standards. Confirm the 'CAH' designation corresponds to the required 3.3V output and ±0.08% accuracy grade. Ensure the ordering quantity matches the available reel or cut-tape packaging options provided by authorized distributors. Cross-reference the datasheet revision date to ensure compatibility with latest thermal and electrical specifications.

Selection Notes

Select this component when a 3.3V reference with ±0.08% initial accuracy is required. It is suitable for applications needing operation up to +105°C junction temperature. Compare against other ISL60002 variants if different output voltages or accuracy grades are needed. Consider the 7mA sink capability for driving moderate loads without external buffering. Verify that the SOT-23-3 package fits the PCB layout constraints.

Part Context

This part belongs to the ISL60002 series of low-power, high-precision voltage references manufactured by Renesas Electronics (formerly Intersil). The series offers various output voltages and accuracy grades using FGA technology. The ISL60002CAH333Z specifically targets applications demanding tight tolerance and stability in a small footprint. It complements other PMIC components in complex power management architectures.

Replacement Considerations

Direct substitutes include other ISL60002 variants with matching 3.3V output and similar accuracy, such as ISL60002BAH333Z or ISL60002DAH333Z, depending on the required initial accuracy tolerance. Verify pinout compatibility and thermal performance before substitution.
