5962L9583401VFA

Overview

The National Semiconductor 5962L9583401VFA is a military-grade analog-to-digital converter (ADC) belonging to the L95834 family. It features a 12-bit resolution with a sampling rate of 1 MSPS. The device utilizes a single +5V power supply and incorporates an internal reference voltage source. It employs a pipelined architecture to achieve high throughput while maintaining low power consumption, typically around 175 mW. The component is housed in a 28-lead ceramic dual in-line package (CDIP) designed for harsh environments.

Feature Summary

• Military-grade qualification ensuring reliability under extreme conditions
• Internal reference voltage eliminates external component requirements
• Pipelined architecture supports high-speed data conversion
• Single-supply operation simplifies power design

Applications

• Military radar signal processing systems
• Avionics instrumentation and control
• Spacecraft telemetry data acquisition
• High-reliability industrial measurement equipment

Procurement Notes

Verify authenticity through authorized distributors or direct manufacturer channels due to the prevalence of counterfeit military-grade components. Confirm lot traceability and mil-spec compliance documentation upon receipt. Check for recent process change notifications that may affect pin compatibility or electrical characteristics. Ensure storage conditions meet moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component when strict MIL-STD-883 compliance is required for 12-bit ADC applications. Compare against commercial equivalents if environmental ruggedness is not critical. Consider the fixed 1 MSPS speed and 5V supply constraints during system architecture planning. Evaluate thermal management needs based on the specified power dissipation in enclosed military enclosures.

Part Context

This part number represents a specific variant within the National Semiconductor L95834 family, tailored for defense and aerospace markets. National Semiconductor was acquired by Texas Instruments, which now manages the legacy product line. The 'L' prefix indicates military temperature range and enhanced screening processes compared to commercial versions.

Replacement Considerations

Direct replacements are limited due to the specialized military specification. Verify pinout compatibility with TI's current offerings in the same family. Cross-reference with other manufacturers' MIL-STD qualified ADCs only after confirming identical electrical parameters and mechanical dimensions.
