EL8401IU

Instrumentation, Op Amps, Buffer Amps Overview

The EL8401IU is a quad-channel, general-purpose operational amplifier manufactured by Renesas Electronics Corporation (formerly Elantec). It features a -3dB bandwidth of 200 MHz and a slew rate of 200V/µs. The device operates on supply voltages ranging from 3V to 5.5V with a low supply current of 2mA per channel. It offers rail-to-rail output capability and inputs that extend to 0.15V below the negative supply rail. Key electrical parameters include an input bias current of 1.6 µA, input offset voltage of 800 µV, and an output current per channel of 65 mA. It is housed in a 14-SOIC package and specified for operation between -40°C and +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 swing capability for maximum dynamic range utilization
• Low power consumption with only 2mA supply current per channel
• Extended common-mode input range extending 0.15V below the negative supply rail

Instrumentation, Op Amps, Buffer Amps Applications

• Video signal processing and amplification
• Portable and hand-held electronic products
• Communication devices requiring high-speed signal conditioning
• General purpose instrumentation circuits

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors as the EL8401 series may have legacy status. Confirm RoHS compliance requirements against specific datasheet revisions, as older batches may not meet current environmental standards. Ensure the 14-SOIC package dimensions match PCB footprint specifications precisely. Check for potential obsolescence notices or lifecycle changes from Renesas Electronics before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple high-speed channels are required within a compact surface-mount footprint. The 200MHz bandwidth suits applications demanding fast signal settling times. Consider the 1.6µA input bias current for moderate impedance source driving. Verify that the 65mA output current meets load requirements without external buffering. Compare against the EL8201 if fewer channels suffice to reduce board space and power usage.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL8401 belongs to the EL8200/EL8201/EL8401 family of 200MHz rail-to-rail amplifiers designed by Intersil, now part of Renesas Electronics. This family shares core performance characteristics including the 200V/µs slew rate and low supply current. The EL8401 specifically provides quad-channel functionality, distinguishing it from the dual-channel EL8201 and single-channel EL8200 variants which offer similar speed and power profiles.
