EL5133IWZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL5133IWZ-T7 is a single-channel, ultra-low voltage noise, high-speed voltage feedback amplifier manufactured by Renesas Electronics Corporation. It features a 670MHz -3dB bandwidth and a 1000V/µs slew rate with an input noise voltage of 0.9nV/√Hz. The device operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±6V, drawing a typical supply current of 12mA. It provides 120mA drive performance and maintains stability at gains as low as 10. The component is housed in a 5-lead SOT-23 package and is specified for operation over the -40°C to +85°C temperature range.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'T7' corresponds to the 7-inch tape and reel packaging configuration containing 3,000 pieces per reel. Confirm the 'Z' suffix indicates RoHS compliance and Pb-free plus anneal material sets compatible with standard soldering operations. Ensure the specific variant matches the required 5-lead SOT-23 package format for your PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when application requirements demand exceptionally low input voltage noise combined with high-speed voltage feedback characteristics. It is suitable for designs requiring stable operation at lower closed-loop gains compared to other high-speed amplifiers. Consider the 5-lead SOT-23 package size if board space is limited, while ensuring adequate thermal management for the power dissipation levels associated with the selected supply voltage and load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the EL5132/EL5133 family of 670MHz low noise amplifiers designed for communications and imaging applications. The EL5133 represents the single-channel version packaged in a compact 5-lead SOT-23 form factor, whereas the EL5132 offers dual channels in an 8-lead SOIC package. Both variants share identical electrical performance specifications regarding bandwidth, noise, and drive capability.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The EL5132ISW-T7 serves as a functional substitute within the same family but utilizes an 8-lead SOIC package rather than the 5-lead SOT-23. Direct pin-for-pin replacement is not possible due to the differing package footprints and pin configurations. Designers must evaluate PCB layout changes and potential parasitic differences if substituting between these package types.
