EL5134IS

Overview

The EL5134IS is a single-channel, high-speed voltage feedback operational amplifier manufactured by Renesas Electronics Corporation (formerly Intersil). It features a gain-bandwidth product of 1500MHz and a -3dB bandwidth of 650MHz at a noise gain of +5. The device operates with supply voltages ranging from 5V to 12V single-supply or ±2.5V to ±5V dual-supply. Key electrical specifications include an ultra-low input voltage noise of 1.5nV/√Hz, input current noise of 0.9pA/√Hz, and a typical slew rate of 450V/µs. It draws 6.7mA per amplifier and includes a fast disable function via the CE pin.

Feature Summary

• Ultra-low voltage and current noise performance suitable for sensitive signal processing
• High-speed operation with 650MHz bandwidth and 1500MHz gain-bandwidth product
• Integrated fast disable feature allowing low-power standby mode
• Capable of driving low-impedance loads with 100mA output drive capability

Applications

• Imaging systems requiring low noise amplification
• Instrumentation circuits demanding high precision
• Communications devices utilizing RF and IF stages

Procurement Notes

Verify that the ordering suffix 'IS' corresponds to the 8-lead SOIC package as specified in the official datasheet. Confirm RoHS compliance status if lead-free variants are required, noting that 'ISZ' denotes Pb-Free versions. Ensure the component meets the -40°C to +85°C operating temperature range requirements for your specific application environment before finalizing procurement.

Selection Notes

Select this component when a voltage feedback topology is preferred over current feedback due to feedback element restrictions. It is appropriate for applications requiring stability at gains as low as +5 while maintaining high bandwidth. Consider the integrated disable feature if power management during idle states is necessary. Verify that the 6.7mA supply current aligns with system power constraints.

Part Context

The EL5134IS belongs to a family of ultra-low voltage noise, high-speed voltage feedback amplifiers designed for communications and imaging. It shares characteristics with the EL5135, EL5234, and EL5235, differing primarily in channel count and package options. Built on a proprietary high-speed complementary bipolar process, it offers low distortion and moderate supply current consumption compared to similar high-speed amplifiers.

FAQ

How is the disable function controlled on the EL5134IS?

The EL5134IS is disabled when the CE pin is pulled up to within 1V of the positive supply voltage, placing the output in a high-impedance state. It is enabled by floating the pin or pulling it to at least 3V below the positive supply.

What is the minimum stable gain for the EL5134IS?

The amplifier is stable at gains as low as +5. While it maintains performance down to lower gain settings, the design ensures stability without peaking issues at a noise gain of 5.

Can the EL5134IS operate with a single supply?

Yes, the device can operate with single supplies ranging from 5V to 12V, as well as dual supplies from ±2.5V to ±5V.
