Overview

The HFA1412IB is a high-speed buffer amplifier manufactured by Harris Corporation, now part of Intersil. This integrated circuit contains four independent buffer circuits housed in a 14-pin SOIC package. It is designed for applications requiring rapid signal transmission with minimal distortion. Key electrical specifications include a slew rate of 1700V/µs and a -3dB bandwidth of 350 MHz. The device features an input bias current of 1 µA and an input offset voltage of 2 mV, ensuring precise signal handling in linear amplifier applications.

Feature Summary

• Provides four independent buffer amplifier channels within a single integrated circuit package.
• Delivers high-speed performance characterized by a 1700V/µs slew rate and 350 MHz bandwidth.
• Maintains low input bias current and low input offset voltage for accurate signal buffering.

Applications

• High-speed signal buffering in electronic circuits
• Linear amplifier stages requiring fast transient response
• Instrumentation systems utilizing buffer amplifiers

Procurement Notes

Verify the manufacturer designation, as Harris Corporation's semiconductor assets were acquired by Intersil. Confirm the specific package type is 14-SOIC and check for any suffix variations that may indicate temperature range or packaging differences. Ensure the component status is active if new production is required, and validate the pinout against official datasheets to prevent integration errors.

Selection Notes

Select this component when multiple buffered outputs are needed from a single source with high speed requirements. The 14-SOIC package offers a compact footprint suitable for surface-mount assembly. Consider the 350 MHz bandwidth and 1700V/µs slew rate to ensure compatibility with high-frequency signals. Verify power supply requirements and thermal management needs for the specific application environment.

Part Context
