EL5420CR

Instrumentation, Op Amps, Buffer Amps Overview

The EL5420CR is a quad, high-speed operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 8 MHz and a slew rate of 10 V/µs. The device operates on supply voltages ranging from 4.5 V to 16.5 V single supply or ±2.25 V to ±8.25 V dual supply. It draws 3 mA of operating current per channel and provides an output drive capability of 30 mA. The unit is housed in a 14-TSSOP surface-mount package and is specified for operation within an ambient temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Rail-to-rail input and output functionality maximizes dynamic range across the full supply voltage spectrum.
• High output drive capability of 30 mA supports direct driving of loads without additional buffering stages.
• Common-mode input voltage extends beyond the supply rails, allowing signal processing even when inputs exceed power limits.

Instrumentation, Op Amps, Buffer Amps Applications

• TFT-LCD drive circuits
• Sampling ADC amplifiers
• Portable instrumentation

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors as the EL5420 series has reached end-of-life status. Confirm specific suffix designations against official datasheets to ensure correct packaging and temperature ratings. Check for moisture sensitivity levels and storage conditions prior to soldering. Validate that the supplier provides traceability documentation consistent with Renesas Electronics standards.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring low power consumption alongside high-speed performance. The quad configuration reduces board space compared to using individual single-channel amplifiers. Ensure the application voltage does not exceed the maximum 16.5 V limit. Consider the 14-TSSOP package dimensions during PCB layout planning to accommodate the required thermal dissipation and pin pitch specifications.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL5420CR belongs to the EL5420 family of low-power, high-voltage operational amplifiers. This family includes variants such as the EL5120 (single) and EL5220 (dual). All members share similar electrical characteristics including 12 MHz bandwidth and rail-to-rail I/O. The CR designation typically indicates the commercial temperature grade and TSSOP packaging format within the broader product line.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Official substitutes include EL5420CLZ and EL5420CRZ. Verify pin compatibility and electrical parameters before integration. Cross-reference datasheets to confirm identical package footprints and thermal characteristics.
