EL5132IS

Overview

The EL5132IS is a high-speed voltage feedback amplifier manufactured by Renesas Electronics Corporation (formerly Intersil). It features a gain-bandwidth product of 3000 MHz and a -3dB bandwidth of 670 MHz. The device offers an ultra-low input noise voltage of 0.9 nV/√Hz and a slew rate of 1000 V/µs. It operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±6V, drawing a typical supply current of 12 mA. The part includes a fast disable feature and is housed in an 8-lead SOIC package.

Feature Summary

Procurement Notes

Verify the manufacturer origin as the component was originally produced by Intersil before its acquisition by Renesas. Confirm that the specific ordering suffix matches the required package type and lead finish specifications. Ensure compatibility with the intended operating temperature range and supply voltage requirements.

Selection Notes

Select this component for applications requiring low noise and high speed within a small footprint. Consider the disable pin functionality if power-down states are necessary. Evaluate thermal dissipation requirements based on the load conditions and ambient temperature to ensure safe operation within the specified junction temperature limits.

Part Context

This device belongs to the EL5132/EL5133 family of low-noise amplifiers designed for communications and imaging systems. It utilizes a proprietary high-speed complementary bipolar process to achieve superior noise performance while maintaining moderate power consumption. The family supports various package options including SOIC and SOT-23.

Replacement Considerations

The EL5132ISZ serves as the lead-free compliant alternative to the standard EL5132IS variant.

FAQ

How does the EL5132IS handle capacitive loads?

Capacitive loads can decrease phase margin and cause peaking or oscillation. For optimum AC performance, it is recommended to isolate capacitive loads using a series resistor between 5Ω and 20Ω.

What is the function of the CE pin on the EL5132IS?

The CE pin enables or disables the amplifier. Pulling the CE pin up to within 1V of the positive supply disables the device, placing the output in a high-impedance state and reducing supply current significantly.
