EL2357CN

Overview

The EL2357CN is a dual-channel, single-supply operational amplifier manufactured by Elantec Semiconductor. It features a bandwidth of 125 MHz and a slew rate of 275 V/µs, designed for video-speed applications. The device operates on +3V, +5V, or ±5V supplies with a low supply current of 5 mA per channel. Key electrical parameters include a maximum offset voltage of 4 mV, an output current capability of ±100 mA, and an open-loop gain of 80 dB. It supports rail-to-rail input common-mode range from 0V to VS - 1.2V and includes output voltage clamping functionality.

Feature Summary

• High-speed performance with 125 MHz bandwidth and 275 V/µs slew rate suitable for video applications
• Single-supply operation compatible with +3V, +5V, and ±5V power rails
• Wide input common-mode range extending from ground to near the positive supply rail
• Integrated output voltage clamping to protect downstream components

Applications

• Video amplifiers
• A/D drivers
• Line drivers
• Active filtering circuits
• High-speed communications systems

Procurement Notes

Verify the manufacturer source as Elantec Semiconductor has undergone corporate changes. Confirm the specific package type and pinout compatibility with your PCB layout. Check for RoHS compliance status if required for your assembly process. Ensure the operating temperature range meets your environmental specifications. Validate that the dual-channel configuration fits your system design requirements.

Selection Notes

Select this component when high bandwidth and fast transient response are critical for signal integrity. The dual-channel architecture reduces board space compared to single-channel alternatives. Consider the low supply current for battery-powered or energy-efficient designs. The wide input common-mode range simplifies biasing in single-supply systems without requiring complex level shifting networks.

Part Context

The EL2357CN belongs to the EL2257C/EL2357C family of single-supply op amps. This series was designed to overcome the bandwidth limitations of earlier single-supply devices. It offers significantly higher speed than competitors while maintaining low power consumption. The dual-channel version provides two independent amplifiers in one package for cost-effective multi-channel applications.

FAQ

What is the maximum supply voltage for the EL2357CN?

The device is specified for +3V, +5V, or ±5V applications.

Does the EL2357CN support rail-to-rail output?

The output swings to ground without saturating, but full rail-to-rail swing is not explicitly guaranteed for the positive rail in all conditions.

What is the differential gain specification?

The differential gain is specified at 0.05%.
