EL4093CSZ-T13

Overview

The EL4093CSZ-T13 is a complete DC-restored video amplifier subsystem manufactured by Renesas Electronics Corporation. It integrates a current feedback amplifier and a sample-and-hold amplifier to stabilize video performance. The device features a 300MHz bandwidth, a 1500V/µs slew rate, and a typical supply current of 9.5mA. It operates within an ambient temperature range of -40°C to +85°C and is housed in a 16-pin SOIC package.

Feature Summary

• Integrates a high-speed current feedback amplifier with a sample-and-hold circuit for precise DC restoration.
• Features a TTL-compatible HOLD logic input that controls the transition between sampling and holding modes.
• Provides a high-impedance current output stage from the sample-and-hold section to simplify interfacing with the video amplifier.

Applications

• Input amplification in professional video equipment
• DC restoration in video mixers

Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete. Confirm datasheet revision FN7159 Rev 0.00 matches requirements. Check RoHS compliance status and moisture sensitivity level MSL 3 before procurement. Ensure thermal management aligns with absolute maximum ratings.

Selection Notes

Select this component for applications requiring high bandwidth and low power consumption in video signal processing. Verify compatibility with ±5V power supplies and ensure proper PCB layout to minimize parasitic capacitance at the inverting input. Consider the specific hold capacitor value required for stability in your design.

Part Context

This device belongs to the EL4093 series of video amplifiers designed for high-speed applications like SVGA and NTSC. Originally produced by Intersil, it was acquired by Renesas Electronics Corporation. The product line focuses on providing integrated solutions for video signal conditioning and restoration.

Replacement Considerations

No recommended replacement is available. The datasheet explicitly states this is an obsolete product with no direct substitute provided by the manufacturer.

FAQ

How does the autozero mechanism function?

The sample-and-hold amplifier compares the video amplifier output to a DC reference. Any difference generates an output current fed to the inverting input, driving the output toward the reference voltage during the sample period.

What is the minimum recommended hold capacitor value?

A hold capacitor of 2.2nF is recommended to ensure loop stability across the entire operating temperature range (-40°C to +85°C).
