EL5444CU

Instrumentation, Op Amps, Buffer Amps Overview

The EL5444CU is a quad, voltage-feedback, high-speed operational amplifier manufactured by Elantec Semiconductor. It operates on a single +5V supply and features rail-to-rail output swing. The device provides unity gain stability with an unloaded -3dB bandwidth of 100MHz and a slew rate of 200V/µs. It includes power-down functionality consuming 2.6µA and differential gain/phase of 0.1%/0.1°. Packaged in an 8-lead MSOP, it is designed for composite and component video applications.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer designation carefully, as Elantec Semiconductor assets were acquired by Renesas Technology Corp. Ensure the datasheet corresponds to the specific Elantec era documentation or its direct successor equivalent. Confirm package integrity and RoHS compliance status against current regulatory requirements before integration into production designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for single-supply +5V analog signal processing where high speed and low power are critical. The 100MHz bandwidth suits high-speed communications and portable computer interfaces. Consider the 8-lead MSOP package for space-constrained layouts requiring quad amplifier density without sacrificing performance metrics.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the EL54xx series of single-supply rail-to-rail amplifiers. It shares architectural similarities with the EL5144 series but is optimized for specific video and general-purpose high-speed applications. The EL5444CU represents the commercial grade variant within this family, offering standard operating temperature ranges suitable for consumer electronics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Renesas EL5444 variants serve as direct successors due to corporate acquisition. Verify pinout compatibility and electrical parameter equivalence when substituting with Intersil or Elantec legacy stock.
