EL5144CW-T7A

Overview

The EL5144CW-T7A is a single-channel, voltage-feedback operational amplifier from the EL5144 series. It operates on a single +5V supply with a typical gain-bandwidth product of 60 MHz and a -3dB bandwidth of 100 MHz at unity gain. The device features a slew rate of 200 V/µs and an input common-mode range extending from ground to within 1.5V of the positive rail. It provides rail-to-rail output swing, sourcing up to 90mA and sinking 65mA. The part is housed in a 5-pin SOT-23 package and operates over an industrial temperature range of -40°C to +85°C.

Feature Summary

• Rail-to-rail output capability allows signal swings close to both supply rails.
• High-speed performance with 100MHz bandwidth and 200V/µs slew rate.
• Single-supply operation optimized for +5V applications.
• Low power consumption with 35mW dissipation per amplifier.

Applications

• Video amplifiers
• Line drivers
• Multiplexers
• Sample & hold amplifiers

Procurement Notes

Verify the specific ordering suffix 'T7A' corresponds to the 7-inch tape and reel packaging containing 250 pieces as documented in the manufacturer's ordering information. Confirm that the component is sourced from authorized channels to ensure authenticity, as the EL5144 series may have legacy availability status depending on the current production cycle.

Selection Notes

Select this component for high-speed, single-supply applications requiring rail-to-rail output. Note that the EL5144 variant lacks the Chip Enable (CE) pin found in EL5146 and EL5246 models; therefore, it does not support power-down functionality. Ensure feedback resistor values are kept between 300Ω and 1kΩ for optimal stability at gains greater than unity.

Part Context

The EL5144CW-T7A belongs to the EL5144 series of wide-bandwidth, low-power, rail-to-rail output amplifiers manufactured by Renesas Electronics Corporation (formerly Intersil). This series includes single, dual, and quad configurations designed for composite and component video applications. The family shares similar electrical characteristics but varies in channel count and the inclusion of power-saving disable features in specific variants.

FAQ

Does the EL5144CW-T7A include a power-down feature?

No, the EL5144 model does not have a Chip Enable (CE) pin or power-down feature. Only the EL5146 and EL5246 variants in this series offer the ability to reduce supply current to 2.6µA via the CE pin.

What is the recommended feedback resistor value for stable operation?

For optimum performance, especially at gains greater than +1, the feedback resistor should be kept between 300Ω and 1kΩ. Using RF = 0Ω is optimal for a gain of +1.
