ICL8069ACSA

Overview

The ICL8069ACSA is a precision shunt voltage reference 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 an initial accuracy tolerance of ±0.5%. The device operates within a junction current range up to 5 mA and supports an operating temperature range from 0°C to +70°C. It is housed in an 8-SOIC surface-mount package.

Feature Summary

• Provides a stable 1.23 V reference output suitable for low-voltage applications
• Features a low temperature coefficient of 50 ppm/°C for thermal stability
• Offers high initial accuracy with a ±0.5% tolerance
• Designed as a shunt reference requiring minimal external components

Applications

• Portable battery-powered instrumentation
• Handheld meters
• Data acquisition systems
• Battery chargers

Procurement Notes

Verify the specific suffix 'ACSA' against official datasheets to confirm the ±0.5% accuracy grade and commercial temperature range (0°C to +70°C). Confirm the 8-SOIC package type matches the design requirements. Check for end-of-life status or obsolescence notices, as older Maxim parts may have limited availability or require alternative sourcing strategies.

Selection Notes

Select this component when a precise 1.23 V reference is needed in space-constrained designs. The 8-SOIC package allows for surface-mount assembly. Ensure the application current does not exceed the maximum shunt current rating. Compare against other ICL8069 variants if higher accuracy or wider temperature ranges are required.

Part Context

The ICL8069 series belongs to the family of low-voltage precision references designed for portable electronics. These devices utilize bandgap technology to achieve stability over temperature and time. The ICL8069ACSA specifically targets cost-sensitive applications requiring moderate precision without the complexity of adjustable references.

Replacement Considerations

Check for direct cross-references such as MAX8069ACSA or ICL8069BCSA depending on accuracy and temperature requirements. Verify pinout compatibility before substitution.
