ICL8069DCBAT

Overview

The ICL8069DCBAT is a fixed shunt voltage reference IC manufactured by Harris Corporation. It provides a stable 1.2V output with a maximum operating current of 5 mA. The device is housed in an 8-SOIC surface-mount package. It operates within a temperature range of 0°C to 70°C and exhibits low noise characteristics, specifically 5µVrms over the 10Hz to 10kHz frequency band. The component utilizes band-gap principles for stability at reverse currents down to 50µA.

Feature Summary

• Low bias current capability suitable for power-sensitive designs
• Low dynamic impedance for stable regulation
• Low noise performance in critical frequency ranges

Applications

• Analog-to-digital converters
• Digital-to-analog converters
• Threshold detectors
• Voltage regulators
• Battery operated equipment

Procurement Notes

Verify the RoHS status carefully as sources indicate non-compliance. Confirm the manufacturer origin, noting potential transitions from Harris to Intersil or other entities. Ensure the 8-SOIC package matches your PCB footprint requirements. Validate the specific suffix 'BAT' against official documentation to confirm tape-and-reel packaging and exact electrical tolerances before finalizing procurement.

Selection Notes

Select this component when a precise 1.2V reference is required in space-constrained applications. The 8-SOIC package facilitates surface-mount assembly. Consider its low power consumption for battery-operated systems. Verify that the 0°C to 70°C operating range meets your environmental specifications. Ensure the 5µVrms noise level is sufficient for your signal integrity needs.

Part Context

This part belongs to the ICL8069 series of low-voltage references. It shares functional similarities with parts like the ICL8069DCBA but differs in packaging and potentially manufacturing lineage. The series is designed for precision applications requiring stable voltage references with minimal power draw. Harris Corporation originally developed these components before corporate restructuring affected production lines.
