EL5151IW-T7

Overview

The EL5151IW-T7 is a single-channel, voltage feedback operational amplifier with a -3dB bandwidth of 200MHz. It features a typical slew rate of 67V/µs and an open-loop gain of 50kV/V. The device operates from single supplies of 5V to 12V or dual supplies of ±2.5V to ±5V, drawing a supply current of 1.4mA. Key electrical parameters include a maximum input offset voltage of 1mV, a common-mode rejection ratio of 85dB, and a power supply rejection ratio of 80dB. It is housed in a 5-lead SOT-23 package.

Feature Summary

• Provides high-speed signal processing with a 200MHz bandwidth and low power consumption suitable for portable equipment.
• Features very high DC accuracy with minimal offset voltage and temperature coefficient for precision measurement applications.
• Includes a dedicated disable pin that reduces supply current to microampere levels when the amplifier is not in use.

Applications

• Precision measurement instrumentation
• High speed video and monitor circuits
• Imaging systems
• Communications devices

Procurement Notes

Verify the specific ordering suffix 'T7' corresponds to tape and reel packaging as defined in Intersil documentation TB347. Confirm RoHS compliance status by checking for the 'Z' suffix variant if lead-free requirements are mandatory. Ensure the component source matches Renesas Electronics Corporation specifications given historical corporate acquisitions.

Selection Notes

Select this component for designs requiring wide bandwidth combined with low quiescent current. The internal compensation allows stability at closed-loop gains of +1 or greater. Verify that the required load resistance and capacitive drive capabilities align with the application's output impedance needs to maintain phase margin.

Part Context

This part belongs to the EL5150 family of wide bandwidth, low power amplifiers. It shares architectural similarities with the EL5150, EL5250, EL5251, and EL5451, differing primarily in channel count and package configuration. The EL5151 specifically offers a single amplifier in a compact SOT-23 form factor.

FAQ

What is the function of the CE pin on the EL5151?

The CE (Chip Enable) pin controls the power-down state. Driving this pin above VS+ - 1.5V disables the amplifier, reducing supply current significantly, while floating it or applying a low signal enables normal operation.

How does load resistance affect the bandwidth of the EL5151?

Bandwidth is dependent on the load resistance. For example, driving a 500Ω load yields approximately 200MHz bandwidth, whereas driving a 150Ω load at a gain of +2 reduces the bandwidth to about 40MHz.
