EL5251IS-T7

Overview

The EL5251IS-T7A is a dual-channel, voltage-feedback operational amplifier from the EL5150 family. It features a -3dB bandwidth of 200MHz and a gain-bandwidth product of 40MHz. The device operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±5V with a typical supply current of 1.35mA per channel. Key electrical parameters include a slew rate of 67V/µs, an input offset voltage of 1mV maximum, and an open-loop gain of 50kV/V. It is housed in an 8-lead SOIC package.

Feature Summary

• Dual-channel architecture providing two independent amplifiers within a single integrated circuit.
• High-speed performance characterized by a 200MHz bandwidth and 67V/µs slew rate for fast signal processing.
• Low power consumption suitable for battery-powered equipment with minimal quiescent current draw.
• Integrated disable functionality that reduces supply current significantly when the amplifier is powered down.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation, as variations exist between standard tape-and-reel packaging and lead-free (RoHS compliant) specifications. Confirm the manufacturer designation, noting historical transitions from Intersil to Renesas Electronics Corporation. Ensure the component status is reviewed prior to design-in, as availability may be affected by end-of-life notices.

Selection Notes

Select this component for designs requiring high bandwidth and low power consumption in a compact form factor. The dual-channel configuration allows for cost-effective implementation of differential circuits or multi-stage filtering. Verify that the required load resistance and capacitive drive capabilities align with the application's stability requirements to prevent peaking or oscillation.

Part Context

This part belongs to the EL5150 family of wide-bandwidth, low-power operational amplifiers. The family includes single, dual, and quad variants such as the EL5150, EL5250, and EL5451. These amplifiers are internally compensated for closed-loop gains of +1 or greater and are designed for industrial temperature ranges from -40°C to +85°C.

FAQ

What is the input common mode voltage range?

The input common mode voltage ranges from 3.5V above the negative supply (VS-) to 3.5V below the positive supply (VS+).

How does the disable pin affect power consumption?

When disabled via the CE pin, the supply current is reduced to approximately 12µA to 17µA typically, effectively eliminating power consumption during standby.

What is the recommended feedback resistor value for optimal response?

A feedback resistance ranging from 500Ω to 750Ω provides optimal response for gains greater than unity.
