4214BP

Overview

The Burr-Brown 4214BP is a monolithic analog multiplier and divider integrated circuit designed for high-precision signal processing applications. It operates as a four-quadrant device, capable of performing multiplication and division functions with inputs in any polarity combination. The component is housed in a 14-pin Ceramic Dual In-Line Package (CDIP) with a 0.300-inch (7.62mm) width, featuring a windowed configuration suitable for UV erasure or specific packaging requirements. This IC is part of the Burr-Brown legacy product line, now managed under Texas Instruments instrumentation solutions.

Feature Summary

• Provides precise analog multiplication and division capabilities across all four quadrants
• Monolithic construction ensures stable performance and reduced external component count
• Windowed ceramic dual in-line package design for robust industrial environments

Applications

• Signal modulation and demodulation circuits
• Automatic gain control systems
• Frequency synthesis and mixing applications

Procurement Notes

Verify component authenticity carefully due to obsolete status and potential availability from third-party distributors. Confirm package integrity and pin compatibility before integration. Check RoHS compliance documentation for specific manufacturing lots. Ensure supply chain stability as this is a legacy part no longer in active mass production by the original manufacturer.

Selection Notes

Select this component when four-quadrant analog multiplication or division is required in a ruggedized environment. The CDIP package offers superior thermal and mechanical stability compared to plastic variants. Consider interface voltage ranges and accuracy specifications against system requirements. Evaluate alternative modern equivalents if long-term supply assurance is critical for the product lifecycle.

Part Context

The 4214BP belongs to the Burr-Brown family of precision analog multipliers. Burr-Brown was acquired by Texas Instruments, which continues to support these legacy parts through its instrumentation amplifier portfolio. The 4214 series represents a standard solution for linear analog computation tasks prior to the widespread adoption of digital signal processing techniques.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Users should consult official Texas Instruments documentation for current equivalent recommendations or cross-reference with other manufacturers offering four-quadrant analog multipliers.
