EL5420CS

Instrumentation, Op Amps, Buffer Amps Overview

The EL5420CS is a quad voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, enabling maximum dynamic range across supply voltages from 4.5 V to 16.5 V. The device operates with a gain bandwidth product of 8 MHz and a -3 dB bandwidth of 12 MHz. Each channel draws 500 µA of supply current, resulting in low power consumption. Key electrical parameters include a slew rate of 10 V/µs, an input bias current of 2 nA, and an input offset voltage of 2 mV. It provides a high output drive capability of 30 mA per channel and functions within an ambient temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized channels as the EL5420CS is listed as obsolete. Confirm package integrity and pin alignment against the 14-SOIC specification. Check for RoHS compliance status, as standard versions may not meet current environmental regulations. Ensure replacement components match the required electrical characteristics and thermal performance before integration into new designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption combined with high voltage operation up to 16.5 V. The rail-to-rail I/O feature makes it suitable for single-supply systems where maximizing signal swing is critical. Consider the 14-SOIC package constraints for board space. Evaluate the 8 MHz bandwidth and 10 V/µs slew rate against signal frequency requirements to ensure adequate performance without distortion.
