HA1-2557-9

Overview

The HA1-2557-9 is a four-quadrant analog multiplier manufactured by Harris Corporation. It is housed in a 16-pin Ceramic Dual In-Line Package (CERDIP). This component functions as an analog multiplier and divider, designed for precision signal processing applications requiring high linearity and wide dynamic range.

Feature Summary

• Four-quadrant analog multiplication capability
• Analog division functionality
• Ceramic dual in-line package construction

Applications

• Signal modulation systems
• Frequency mixing circuits
• Automatic gain control loops

Procurement Notes

Verify the specific suffix '-9' against the manufacturer's current datasheet to confirm pinout compatibility and ceramic package specifications. Ensure the source document explicitly identifies this part as a Harris Corporation product to avoid confusion with generic equivalents or updated series revisions.

Selection Notes

Select this component when a hermetically sealed ceramic package is required for environmental stability. The four-quadrant operation supports both positive and negative input signals, making it suitable for complex analog computation tasks where bipolar signal handling is necessary.

Part Context

This device belongs to the Harris Corporation linear integrated circuit family, specifically categorized under analog multipliers and dividers. It represents the ceramic DIP variant of the 2557 series, distinguishing it from plastic packaged versions like the HA3-2557-9.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify functional equivalence with other four-quadrant analog multipliers if direct replacement is required.
