HFA1305IB

Overview

The HFA1305IB is a high-speed current feedback operational amplifier manufactured by Harris Corporation, now part of Renesas Electronics. It features a single channel with a slew rate of 2.3 kV/us and an input offset voltage of 6 mV. The device operates on a supply voltage range of 4.5 V to 5.5 V, consuming 26 mA of quiescent current. It offers low input voltage noise density of 4 nV/sqrt Hz and input bias current of 40 uA. Packaged in SOIC-8 for surface mount installation, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• High-speed current feedback architecture for rapid signal processing
• Integrated clamp protection for enhanced circuit reliability
• Industrial temperature rating for robust environmental performance

Applications

• Video signal processing circuits

• Broadband communication equipment

Procurement Notes

Verify the manufacturer status as this component may be discontinued or superseded by newer generations from Renesas. Confirm RoHS compliance details through official datasheets before integration. Ensure availability checks are performed via authorized distributors as stock levels vary. Validate pin compatibility if replacing existing designs.

Selection Notes

Select this component for applications requiring high slew rates and wide bandwidths typical of current feedback amplifiers. Consider the SOIC-8 package constraints for PCB layout. Evaluate the 4.5 V to 5.5 V supply requirement against system power rails. Compare noise specifications against other high-speed op-amps for optimal signal integrity.

Part Context

This part belongs to the HFA1130 series of high-speed operational amplifiers. It represents the industrial grade variant of the HFA1305 family. The series is known for combining high speed with low power consumption in a compact form factor. It was originally developed by Harris Semiconductor before corporate acquisitions.

Replacement Considerations

Check for direct replacements such as the HFA1305IBZ or updated Renesas equivalents. Verify functional compatibility regarding pinout and electrical characteristics. Ensure thermal management requirements remain consistent with the new component.
