• High bandwidth performance for video signals
• Low input offset voltage and bias current
• Supports reactive or non-linear feedback loops

Applications

• High resolution video systems
• Active filters
• Integrators
• Sample-and-hold circuits
• Logarithmic amplifiers

Procurement Notes

Verify the manufacturer status as Elantec Semiconductor may be part of Renesas Electronics. Confirm the specific suffix 'CS' indicates the correct package type and temperature range. Check for end-of-life status or obsolescence notices from authorized distributors. Ensure compatibility with existing PCB footprints for the SO-8 package. Validate that the current-feedback topology meets the system requirements instead of voltage-feedback alternatives.

Selection Notes

Select this component when a current-feedback amplifier is required for high-speed applications. The 200MHz bandwidth suits video and RF signal processing tasks. Consider the low offset voltage for precision analog front ends. Verify that the circuit design accommodates the current-feedback nature, which differs from standard voltage-feedback op-amps. Ensure the power supply rails match the device specifications for optimal performance.

Part Context

The EL2070CS belongs to the Elantec video amplifier family, specifically designed for fast settling and high bandwidth. It is distinct from the EL2074C, which is a voltage-feedback amplifier with a 400MHz gain-bandwidth product. The EL2070CS utilizes a current-feedback topology, offering different stability characteristics and feedback loop flexibility compared to its voltage-feedback counterparts in the same series.
