HFA1105IBZ

Overview

The HFA1105IBZ is a single-channel, low-power current feedback video operational amplifier manufactured by Renesas Electronics. It features a bandwidth of 330 MHz and a typical slew rate of 2300 V/µs. The device operates on dual supply voltages with a typical value of ±5V and supports an operating temperature range from -40°C to +85°C. Packaged in an 8-pin SOIC format measuring 5 x 4 x 1.5 mm, it draws 21 mA of supply current.

Feature Summary

• High-speed current feedback architecture optimized for video signal processing applications
• Low power consumption design suitable for portable or battery-operated systems
• Single-channel configuration providing dedicated amplification for one circuit path

Applications

• Video buffering and line driving circuits
• Signal conditioning for high-frequency analog video signals
• Test and measurement equipment requiring fast transient response

Procurement Notes

Verify the specific suffix (e.g., Z96) against the original design specification to ensure correct packaging and lead finish compatibility. Confirm that the manufacturer designation aligns with Intersil or Renesas Electronics as historical ownership transitions may affect documentation sources. Ensure the component meets RoHS compliance requirements if mandated by the target market regulations.

Selection Notes

Select this component when a current feedback topology is required for wideband video applications rather than voltage feedback alternatives. Consider the 330 MHz bandwidth limit relative to the highest frequency components in the signal chain. Evaluate the ±5V dual supply requirement against available system power rails to determine if level shifting or additional regulation is necessary for proper operation.

Part Context

This part belongs to the HFA1100 series of video operational amplifiers designed for high-speed signal integrity. It shares architectural similarities with other members like the HFA1100 and HFA1130 but offers specific performance trade-offs between bandwidth and power consumption. The series is characterized by its bipolar process technology and suitability for professional video infrastructure.
