EL2141CSZ

Overview

The EL2141CSZ is a high-bandwidth differential twisted pair driver manufactured by Renesas Electronics Corporation (formerly Intersil). It features fully differential inputs, outputs, and feedback with a 150MHz -3dB bandwidth. The device operates on ±5V supplies or +6V single supply, providing an 800 V/µs slew rate and 50mA minimum output current. It includes a reference pin for output common-mode control and short-circuit protection.

Feature Summary

• Fully differential input, output, and feedback architecture
• Adjustable voltage gain via external feedback resistors
• Output common-mode level controlled by the VREF pin
• Short-circuit protected outputs

Applications

• Twisted pair line drivers
• ADSL/HDSL signal transmission
• Single-ended to differential amplification
• Video graphics adapter (VGA) over twisted pair

Procurement Notes

Verify the manufacturer origin as the component was originally produced by Intersil before its acquisition by Renesas. Confirm that the 'S' suffix denotes the 8-pin SOIC package and the 'Z' indicates lead-free compliance. Ensure the operating temperature range matches the specified -40°C to +85°C for your application environment.

Selection Notes

Select the EL2141CSZ when adjustable gain is required, as opposed to the fixed-gain EL2140. Consider the 150MHz bandwidth and low distortion characteristics for high-frequency signal integrity. Evaluate power supply requirements against the ±5V or +6V single supply options. Account for layout constraints regarding stray capacitance on feedback nodes to prevent gain peaking.

Part Context

This component belongs to the EL2140/EL2141 family of differential amplifiers designed for driving twisted pair lines. It utilizes advanced analog design techniques to achieve high bandwidth and low distortion. The EL2141 variant specifically provides user-configurable gain through dedicated feedback pins, offering flexibility in circuit design compared to fixed-gain alternatives.

Replacement Considerations

The EL2140 is a compatible alternative within the same family but features a fixed gain of two. Verify if the specific application requires adjustable gain; if not, the EL2140 may serve as a direct functional substitute. Ensure pin compatibility and thermal performance align with the existing design constraints.
