HFA1105IB

Overview

The HFA1105IB is a single-channel, low-power current feedback video operational amplifier manufactured by Intersil. It features a bandwidth of 330MHz and operates within an industrial temperature range of -40°C to +85°C. The device is housed in an 8-pin SOIC package (PDSO8) and utilizes bipolar technology. Designed for high-speed signal processing, it supports dual power supply configurations.

Feature Summary

• Current feedback architecture optimized for high-speed video applications
• Low power consumption characteristics suitable for portable systems
• Industrial temperature rating ensuring reliable operation in harsh environments

Applications

• Video signal amplification
• High-speed data acquisition systems
• Test and measurement equipment

Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Harris and later acquired by Intersil, which is now part of Renesas Electronics. Confirm the specific suffix indicates standard SOIC-8 packaging without additional annealing or tape-and-reel variations unless explicitly documented. Ensure compatibility with existing PCB footprints for PDSO8 packages.

Selection Notes

Select this component when a single-channel current feedback amplifier with 330MHz bandwidth is required. Consider the bipolar input stage and low power profile against voltage feedback alternatives. Verify that the 8-pin SOIC package fits the mechanical constraints and that the operating temperature range meets the system requirements.

Part Context

This component belongs to the HFA1105 series of video amplifiers. It shares functional similarities with other members like the HFA1105IBZ, differing primarily in packaging or manufacturing lot specifications. The series is characterized by high slew rates and wide bandwidths tailored for professional video and RF signal conditioning tasks.
