LS352 SOIC 8L ROHS

Overview

The LS352 is a precision voltage reference integrated circuit manufactured by Linear Integrated Systems, Inc. It provides a stable 4.096 V output voltage with low temperature coefficient characteristics suitable for high-accuracy applications. The device is housed in an 8-pin Small Outline Integrated Circuit (SOIC) package compliant with RoHS standards. As a series voltage reference, it operates within specified input voltage ranges and maintains initial accuracy across the defined operating temperature range. This component serves as a critical reference source in analog signal processing circuits requiring precise voltage stability.

Procurement Notes

Verify the manufacturer designation carefully as Linear Integrated Systems may be associated with specific legacy or specialized production lines. Confirm the exact suffix codes match the required package type and environmental compliance specifications. Ensure the datasheet aligns with the intended operating temperature range and electrical performance requirements for the specific application design.

Selection Notes

Select this component when a stable 4.096 V reference is required in a compact surface-mount format. Consider the temperature coefficient and initial accuracy specifications against the system's error budget. Evaluate the input voltage headroom requirements to ensure proper regulation under all operating conditions. Compare power consumption metrics if battery life or thermal management is a constraint in the final design.

Part Context

The LS352 belongs to the family of precision voltage reference devices designed for industrial and instrumentation applications. It complements other linear regulators and reference chips by offering a specific 4.096 V output level. This voltage level is often chosen for compatibility with standard ADC/DAC full-scale ranges. The SOIC-8 package allows for easy integration into modern PCB layouts while maintaining the performance benefits of traditional through-hole reference designs.

Replacement Considerations

Check for direct pin-compatible alternatives from manufacturers like Maxim Integrated or Texas Instruments that offer similar 4.096 V outputs. Verify that substitute components meet the same temperature coefficient and accuracy specifications. Ensure the replacement package matches the SOIC-8 footprint and lead pitch to avoid board redesign.
