EL5420CSZ

Instrumentation, Op Amps, Buffer Amps Overview

The EL5420CSZ is a quad voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features rail-to-rail input and output capabilities, allowing for maximum dynamic range across supply voltages ranging from 4.5 V to 16.5 V. The device operates with a gain-bandwidth product of 8 MHz and a slew rate of 10 V/µs. Each channel consumes approximately 500 µA, resulting in a total operating current of 2 mA for the quad configuration. It is housed in a 16-lead SSOP package and supports an ambient temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type and suffix against official Renesas documentation, as the EL5420 series utilizes various suffixes to denote different packages such as TSSOP, SOIC, QFN, and SSOP. Confirm availability status directly with authorized distributors or the manufacturer, as lifecycle changes may affect procurement options. Ensure compliance with RoHS directives and moisture sensitivity levels specified in the datasheet prior to ordering.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the EL5420CSZ when a quad amplifier configuration with rail-to-rail performance is required in a space-constrained design. This part is suitable for applications demanding low power consumption alongside high output drive capabilities. Compare pinout compatibility with existing designs, as the SSOP package differs from other available variants like TSSOP or QFN. Verify that the 8 MHz bandwidth meets the signal processing requirements of the target application.

Instrumentation, Op Amps, Buffer Amps Part Context

The EL5420CSZ belongs to the EL5420 family of low-power, high-voltage, rail-to-rail input-output amplifiers. This family includes single (EL5120), dual (EL5220), and quad (EL5420) configurations. The components are designed for battery-powered and portable devices where low power consumption is critical. They feature fast slewing and settling times, making them versatile for general-purpose analog signal processing tasks.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for direct pin-compatible replacements within the EL5420 family, such as EL5420CRZ or EL5420CLZ, which offer similar electrical characteristics but in different packages. Verify if newer generations of rail-to-rail op-amps from Renesas provide improved specifications while maintaining compatibility.
