EL8403IU

Instrumentation, Op Amps, Buffer Amps Overview

The EL8403IU is a high-speed quad operational amplifier manufactured by Elantec Semiconductor. It features a gain-bandwidth product of 200 MHz and a slew rate of 600 V/µs, supporting rail-to-rail output operation. The device operates on a single supply voltage ranging from 3 V to 5.5 V with a typical quiescent current of 24.8 mA per channel. It provides a voltage gain of 90 dB and an input bias current of 9 µA. The component is housed in a QSOP-16 package and functions within a temperature range of -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Quad-channel architecture providing four independent high-speed amplifiers in a single package
• Rail-to-rail output capability allowing maximum dynamic signal swing
• High slew rate of 600 V/µs for fast transient response applications
• Low power consumption suitable for portable and battery-operated systems

Instrumentation, Op Amps, Buffer Amps Applications

• Video buffering and signal conditioning circuits
• Portable instrumentation requiring high bandwidth and low power
• Active filtering in communication equipment
• Data acquisition systems with high-speed requirements

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer origin carefully as Elantec was acquired by Intersil, which later became part of Renesas Electronics. Ensure the specific suffix matches the required package type and tape/reel configuration. Confirm RoHS compliance status through official datasheets or authorized distributors, as legacy stock may vary in environmental certification.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier configuration is required alongside high slew rates and rail-to-rail output performance. Compare against single-channel alternatives if board space permits, noting that the quad version offers higher integration density. Verify that the 200 MHz gain-bandwidth product meets the specific frequency requirements of the target application circuit design.

Instrumentation, Op Amps, Buffer Amps Part Context

This component belongs to the Elantec EL8403 series of high-speed operational amplifiers. The series is characterized by its combination of wide bandwidth and low power consumption, targeting applications where multiple channels are needed without excessive power draw. The EL8403 variant specifically integrates four amplifiers into a compact surface-mount package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for equivalents from Renesas or Intersil under the same EL8403 family designation. Verify pin compatibility and electrical specifications before substitution.
