HA3-2557-9 is a high-speed four-quadrant analog multiplier with wide bandwidth and high precision, widely used in RF communication, video processing, instrumentation and industrial control

The HA3-2557-9 is a high-speed four-quadrant analog multiplier with wide bandwidth and high precision, manufactured by Harris Corporation (now Intersil). This component is widely used in RF communication, video processing, instrumentation, and industrial control applications.

This high-performance analog multiplier features a 100 MHz -3dB bandwidth and single-ended current output (trimmed to 1.6 mA). It operates from ±15 V power supplies and provides a ±4 V full-scale voltage range via internal feedback resistor. The device maintains exceptional performance with low multiplication error (1.5%) and feedthrough (-50 dB), making it ideal for precision analog computation and high-speed signal conditioning.

• Four-Quadrant Multiplication: Performs accurate multiplication of two analog signals (X and Y) across all four quadrants, supporting both positive and negative input voltages.
• High-Frequency Operation: Delivers 100 MHz bandwidth and high slew rate, enabling signal processing in high-speed communication, video, and RF systems.
• Current-to-Voltage Conversion: Integrates an internal feedback resistor for precise conversion of current output to ±4 V full-scale voltage, eliminating the need for external amplification.
• Precision Performance: Maintains low differential gain/phase errors (0.1%/0.1°) and gain flatness, ensuring signal integrity in critical applications.
