HA1-2556-9

Overview

The HA1-2556-9 is a high-performance analog multiplier integrated circuit manufactured by Renesas Electronics Corporation. It features a four-quadrant voltage output architecture, enabling precise signal processing capabilities across industrial applications. The device is housed in a 16-pin Ceramic Dual In-Line Package (CDIP), designed for robust surface mount or through-hole integration. As an obsolete component within the Analog Multipliers and Dividers category, it serves specialized roles requiring accurate mathematical operations on analog signals.

Feature Summary

• Four-quadrant voltage output capability for comprehensive signal multiplication
• High-performance analog processing suitable for demanding environments
• Robust ceramic dual in-line package construction

Applications

• Integrator and differentiator circuits
• Logarithmic and exponential operation circuits
• Multiplication functions in industrial automation systems

Procurement Notes

Verify part status carefully as this component is listed as obsolete. Confirm availability with authorized distributors or surplus suppliers. Ensure compatibility with existing PCB footprints and thermal requirements. Check for moisture sensitivity level compliance during handling. Validate that the 16-CDIP package matches the target assembly specifications before procurement.

Selection Notes

Select this component only when legacy system compatibility or specific four-quadrant analog multiplication performance is required. Consider the obsolete status for long-term supply chain stability. Evaluate alternative modern analog multipliers if new design implementation is possible. Verify that the ceramic DIP package meets mechanical and environmental constraints of the application.

Part Context

This component belongs to the Analog Multipliers and Dividers category from Renesas Electronics. It represents a legacy product line originally associated with Intersil technology acquired by Renesas. The device provides specialized analog computation functions distinct from standard operational amplifiers or digital signal processors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status of the HA1-2556-9. Engineers should consult official Renesas replacement guides or evaluate generic four-quadrant analog multipliers with compatible pinouts and electrical characteristics.
