EL8403IS

Instrumentation, Op Amps, Buffer Amps Overview

The EL8403IS is a quad channel, wide bandwidth, single supply, low power and rail-to-rail output voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features a -3dB bandwidth of 500MHz and a slew rate of 600V/µs while consuming only 5.6mA per channel. The device operates on supplies from 3V to 5.5V with inputs extending to 0.15V below the negative supply rail. It is housed in a 14-lead Small Outline (SO) package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the component is sourced from authorized channels to ensure authenticity. Confirm the specific package variant matches the required design footprint. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range meets the system requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple high-speed amplification channels are required in a compact form factor. Consider the 500MHz bandwidth and 600V/µs slew rate for fast transient response needs. Evaluate the 5.6mA per channel current consumption against total system power budgets. Verify compatibility with the available supply voltage range between 3V and 5.5V.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the EL8202, EL8203, and EL8403 family of 500MHz Rail-to-Rail Amplifiers. While the EL8202 offers dual channels with a disable feature and the EL8203 provides dual channels, the EL8403 specifically integrates four channels. All variants share identical electrical performance characteristics regarding speed and power consumption.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet explicitly states 'NO RECOMMENDED REPLACEMENT' for this product line. Designers should consult technical support for potential alternatives or consider redesigning the circuit if this component becomes unavailable.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the EL8403IS include a power-down or disable pin?

No, the disable/power-down circuit is a feature exclusive to the EL8202 model. The EL8403 does not have an enable or disable input pin.

What is the input common mode voltage range?

The input common mode voltage range extends from 0.15V below the negative supply rail (VS-) to within 1.5V of the positive supply rail (VS+).
