EL5156ISZ

Overview

The EL5156ISZ is a single-channel, voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features a 600MHz -3dB bandwidth and a typical slew rate of 700V/µs. The device operates on single supplies from 5V to 12V or dual supplies from ±2.5V to ±5V with a supply current of 6mA. Key electrical parameters include an input offset voltage of less than 1mV, an open-loop gain of 40kV/V, and a peak output current capability of 140mA. It includes a fast disable feature for power reduction.

Feature Summary

• Provides high-speed signal processing with a 600MHz bandwidth and 700V/µs slew rate.
• Delivers high DC accuracy with low input offset voltage and high open-loop gain.
• Features a dedicated enable pin that reduces supply current significantly when disabled.
• Capable of driving demanding loads with a peak output current of 140mA.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'ISZ' confirms the lead-free (RoHS compliant) status and the 8-lead SOIC package configuration. Confirm availability as this component may be subject to discontinuation notices. Ensure the application environment supports the specified industrial temperature range and supply voltage requirements.

Selection Notes

Select the EL5156ISZ for designs requiring wide bandwidth combined with low offset voltage in a compact surface-mount package. Consider the disable functionality if power management during idle states is required. Evaluate thermal dissipation capabilities based on the load conditions and ambient temperature to ensure operation within safe junction limits.

Part Context

This component belongs to the EL515x family of amplifiers, which also includes dual-channel variants like the EL5256. The family shares core performance characteristics such as the 600MHz bandwidth and low power consumption, offering flexibility for single or dual-channel system architectures while maintaining consistent high-frequency response and accuracy.

Replacement Considerations

EL5157ISZ: Identical specifications but lacks the disable pin.

FAQ

How does the disable function operate?

The EL5156 includes an enable pin that places the output in a high-impedance state and reduces supply current to approximately 17µA when activated.

What is the recommended feedback resistor value?

For gains greater than +1, optimum response is achieved with feedback resistors between 500Ω and 750Ω.
