ICL8069BCSA

Overview

The ICL8069BCSA is a low-voltage 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 100 PPM/°C. The device supports a maximum shunt current of 5 mA and operates within a temperature range of 0°C to +70°C. It is housed in an SOIC-Narrow-8 surface-mount package.

Feature Summary

• Provides a stable 1.23 V reference output suitable for precision applications
• Utilizes shunt topology for efficient voltage regulation
• Designed for surface-mount integration via narrow SOIC packaging

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Battery-powered instrumentation circuits requiring stable bias

Procurement Notes

Verify component authenticity through authorized distributors due to discontinued status. Confirm package integrity and pin alignment against the SOIC-Narrow-8 specification. Review datasheet revisions for any parameter updates prior to integration into new designs.

Selection Notes

Select this component when a fixed 1.23 V reference is required in space-constrained surface-mount designs. Ensure operating conditions remain within the specified 0°C to +70°C range. Evaluate thermal dissipation capabilities relative to the maximum 5 mA shunt current limit during steady-state operation.
