EL2141CSZ-T13

Overview

The EL2141CSZ-T13 is a high-bandwidth differential amplifier manufactured by Renesas Electronics Corporation, originally designed by Intersil. It features fully differential inputs and outputs with adjustable gain via external feedback resistors, maintaining stability at a minimum gain of two. The device provides an output common-mode level controlled by the VREF pin and includes short-circuit protection for both outputs. Designed for low-distortion signal transmission, it supports single-ended to differential conversion and operates on ±5V supplies or a +6V single supply.

Feature Summary

• Fully differential input and output architecture with configurable voltage gain
• Output common-mode control via dedicated reference pin
• Short-circuit protection on both output terminals
• Low power consumption with typical supply current of 11mA

Applications

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

Procurement Notes

Verify the manufacturer origin as the component was originally developed by Intersil before its acquisition by Renesas. Confirm that the specific suffix corresponds to the tape and reel packaging format required for automated assembly processes. Ensure compatibility with the recommended operating temperature range during system integration.

Selection Notes

Select this component when a fully differential output is required from a potentially single-ended source. The EL2141 allows for flexible gain setting through external resistors, unlike the fixed-gain EL2140 variant. Consider the 150MHz bandwidth and slew rate capabilities for high-frequency signal integrity requirements in communication systems.

Part Context

This part belongs to the EL2140/EL2141 family of differential twisted pair drivers. While the EL2140 offers a fixed internal gain of two, the EL2141 provides user-configurable gain settings via separate feedback inputs. Both devices share identical physical pinouts and package options, differing primarily in their internal circuitry configuration for gain control.

Replacement Considerations

The EL2140 serves as a functional alternative if a fixed gain of two is sufficient for the application. Verify that any substitute maintains the same 8-pin SOIC footprint and differential signaling characteristics to ensure board layout compatibility.
