ICL8069DCSA

Overview

The ICL8069DCSA 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 100 PPM/C. The device supports a maximum shunt current of 5 mA and operates within a commercial temperature range from 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 via shunt topology
• Designed for surface-mount integration using SOIC-Narrow-8 packaging
• Operates reliably across standard commercial temperature ranges

Applications

• Precision analog-to-digital converter reference circuits
• Portable instrumentation requiring low-power references
• Battery-powered measurement systems

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels, as the ICL8069 series may have limited availability or end-of-life status. Confirm package integrity and pin alignment upon receipt. Ensure storage conditions comply with moisture sensitivity level requirements for SOIC packages to prevent soldering defects during assembly.

Selection Notes

Select this component when a compact, low-cost shunt reference is required for commercial-grade applications. The 1.23 V output suits direct interfacing with certain ADCs without additional scaling. Consider the 100 PPM/C temperature coefficient against stricter stability needs; if higher precision is required, evaluate the ICL8069C variant with lower temperature drift.

Part Context

The ICL8069 series belongs to Maxim Integrated's portfolio of micropower voltage references. These devices utilize bandgap technology to generate stable reference voltages. The DC suffix denotes the industrial/commercial temperature grade and specific performance tolerances compared to other variants in the family.
