HFA1109IB

Overview

The HFA1109IB is a low-power, current feedback video operational amplifier manufactured by Intersil. It features a -3dB bandwidth of 450 MHz and a slew rate of 2600 V/µs. The device operates with a supply current of 9.6 mA. It is housed in an 8-SOIC package and is classified under Video Amps and Modules.

Feature Summary

• Current feedback architecture for high-speed performance
• Low power consumption design
• Wide bandwidth suitable for video applications

Applications

• Video signal processing
• High-speed analog circuits
• ADC driver stages

Procurement Notes

Verify the RoHS status carefully as sources indicate non-compliance. Confirm lifecycle status as obsolete before procurement planning. Ensure the 8-SOIC package matches your PCB footprint requirements. Cross-reference datasheet revisions to confirm electrical parameters remain consistent with system specifications.

Selection Notes

Select this component when a current feedback topology is required for wideband video signals. The 450 MHz bandwidth supports high-frequency content. Consider the 9.6 mA supply current for power-constrained designs. Verify compatibility with existing voltage rails and load conditions typical for video amplification tasks.

Part Context
