EL2141CSZ-T7

Overview

The EL2141CSZ-T7 is a high-bandwidth differential amplifier manufactured by Renesas Electronics Corporation. It features a 150MHz -3dB bandwidth and an 800V/µs differential slew rate, designed for driving twisted pair lines in noisy environments. The device operates on ±5V supplies or a +6V single supply, drawing 11mA typical supply current. It provides fully differential inputs and outputs with a minimum stable gain of two. The output common-mode level is controlled via the VREF pin, which offers over 100MHz bandwidth.

Feature Summary

• Fully differential input, output, and feedback architecture
• Low distortion performance optimized for ADSL/HDSL signal transmission
• Adjustable voltage gain with a minimum stable setting of two
• Output common-mode control via dedicated reference pin

Applications

• Twisted pair driver
• ADSL/HDSL driver
• Differential line driver
• Single-ended to differential amplification

Procurement Notes

Verify component authenticity through authorized channels as the EL2141CSZ-T7 may be subject to obsolescence. Confirm package integrity and check for moisture sensitivity indicators prior to assembly. Ensure static discharge precautions are followed during handling. Cross-reference datasheet revisions to confirm electrical specifications match design requirements before finalizing procurement orders.

Selection Notes

Select the EL2141CSZ-T7 when adjustable gain is required for differential signaling applications. Unlike the fixed-gain EL2140, this variant allows external resistor configuration for gains above two. Consider its low power consumption and high bandwidth for noise-sensitive analog signal transmission. Verify that the application load impedance and capacitance limits align with the device's stability characteristics.

Part Context

This component belongs to the EL2140/EL2141 series of high-speed differential amplifiers originally developed by Intersil. The EL2141 variant specifically distinguishes itself from the EL2140 by providing user-configurable gain settings rather than a fixed internal gain of two. Both devices share identical packaging and core differential architecture for driving transmission lines.

Replacement Considerations

The EL2140 serves as a functional alternative if a fixed gain of two is sufficient for the application. Verify compatibility regarding pinout assignments and operating voltage ranges when substituting components within the same family.
