ICL8069CCSA

Overview

The ICL8069CCSA is a shunt voltage reference IC manufactured by Analog Devices Inc./Maxim Integrated. It provides a fixed output voltage of 1.23 V with a temperature coefficient of 50 PPM/°C and a maximum shunt current of 5 mA. The device operates within a temperature range of 0°C to +70°C and is housed in an 8-SOIC surface-mount package.

Feature Summary

• Provides a stable 1.23 V reference voltage for precision applications
• Features low temperature drift characteristics for consistent performance
• Designed as a shunt reference requiring minimal external components

Applications

• Precision analog-to-digital converter (ADC) references
• Digital-to-analog converter (DAC) voltage sources
• Battery-powered instrumentation systems

Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance requirements against specific project standards, as legacy variants may differ. Ensure the 8-SOIC package footprint matches existing PCB layouts before procurement planning.

Selection Notes

Select this component when a low-cost, fixed 1.23 V reference is required for industrial temperature ranges. Consider the 50 PPM/°C stability for applications where higher precision is not critical. Evaluate the 5 mA current limit against load requirements to ensure adequate headroom for regulation.

Part Context

This part belongs to the ICL8069 series of bandgap voltage references. It serves as a fundamental building block in power management integrated circuits (PMICs). The device is designed for general-purpose voltage referencing tasks in mixed-signal systems.
