HFA1305IA

Overview

The HFA1305IA is a high-speed current feedback operational amplifier manufactured by Harris Corporation. It integrates three independent amplifier circuits within a single integrated circuit package. The device is housed in a 16-lead QSOP (Shrink Small Outline Package) with a width of 3.90mm. Key electrical specifications include a slew rate of 2500V/µs, indicating rapid output voltage transition capabilities. The component operates within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrates three independent current feedback amplifier channels for multi-channel signal processing applications.
• Features a high slew rate of 2500V/µs to support high-frequency and fast transient signal handling.
• Utilizes a compact 16-lead QSOP surface-mount package design for efficient PCB layout.

Applications

• High-speed video signal processing systems
• Broadband communication equipment requiring multiple amplifier stages
• Test and measurement instrumentation

Procurement Notes

Verify the manufacturer origin as Harris Corporation or its successors, noting that RoHS compliance status is listed as non-compliant in available records. Confirm the package type is strictly 16-QSOP. Check for any specific lot codes or date codes if vintage sourcing is required, as this component may be discontinued or superseded by newer iterations from the same lineage.

Selection Notes

Select this component when multiple high-speed amplification channels are required in a single footprint. The current feedback architecture offers superior bandwidth stability compared to voltage feedback types under varying gain conditions. Ensure the application can accommodate the 16-pin QSOP form factor and the specified operating temperature range of -40°C to +85°C.

Part Context

This part belongs to the family of high-performance linear amplifiers produced by Harris Semiconductor, which was later acquired by Intersil and subsequently Renesas Electronics. The HFA series is known for utilizing advanced bipolar processes to achieve wide bandwidth and high slew rates, targeting demanding analog signal processing tasks in professional and industrial sectors.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided source data. Designers should consult official successor documentation from Renesas or Intersil for pin-compatible alternatives within the updated product portfolio.
