EL8403ISZ-T7

Instrumentation, Op Amps, Buffer Amps Overview

The EL8403ISZ-T7 is a quad channel, high-speed voltage feedback operational amplifier manufactured by Renesas Electronics Corporation. It features a -3dB bandwidth of 500MHz and a slew rate of 600V/µs. The device operates on supply voltages from 3V to 5.5V with a low quiescent current of 5.6mA per channel. It provides rail-to-rail output swing and an input common mode range extending to 0.15V below the negative supply rail. The component is housed in a 14-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Quad channel configuration providing four independent high-speed amplifiers within a single integrated circuit.
• Rail-to-rail output capability allowing signal swings close to both positive and negative supply rails.
• Wide input common mode range that extends 0.15V below the negative power supply terminal.

Instrumentation, Op Amps, Buffer Amps Applications

• Video amplifiers
• Portable and hand-held products
• Communications devices

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'T7' corresponds to the required tape and reel packaging format for automated assembly processes. Confirm the 'IS' designation matches the required industrial temperature operating range of -40°C to +85°C. Ensure the datasheet revision aligns with current design specifications before finalizing procurement orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad channel topology is required alongside high bandwidth and fast transient response characteristics. The low supply current consumption makes it suitable for battery-operated systems requiring multiple signal processing channels. Verify that the load requirements are compatible with the specified linear output current capabilities.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the EL8202, EL8203, and EL8403 family of wideband, single-supply, low-power rail-to-rail output voltage feedback operational amplifiers. While the EL8202 offers dual channels with a disable feature and the EL8203 provides dual channels without disable, the EL8403 specifically delivers four channels for multi-channel signal conditioning applications.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The manufacturer documentation explicitly states that there is no recommended replacement for this product line. Designers should consider redesigning the circuit or utilizing alternative components from other manufacturers if this part becomes unavailable.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the EL8403 include a power-down or disable pin?

No, the disable/power-down functionality is exclusive to the EL8202 variant within this family. The EL8403 does not feature an enable pin.

What is the maximum supply voltage for the EL8403?

The absolute maximum supply voltage from VS+ to VS- is 5.5V. The recommended operating supply range is between 3V and 5.5V.
