EL1517BISZ

Overview

The EL1517BISZ is a high-speed, low-power CMOS operational amplifier manufactured by Elantec Semiconductor. It features a rail-to-rail output stage and operates from a single supply voltage ranging from 2.7V to 36V or dual supplies of ±1.35V to ±18V. The device offers a gain-bandwidth product of 10MHz and a slew rate of 14V/µs, ensuring fast signal response in demanding applications. With a maximum input offset voltage of 2mV and low quiescent current consumption, it is suitable for battery-powered and portable equipment. The component is housed in an 8-lead SOIC surface-mount package.

Feature Summary

• Rail-to-rail output capability allows the output voltage to swing close to both supply rails, maximizing dynamic range in low-voltage systems.
• High-speed performance with a 10MHz gain-bandwidth product and 14V/µs slew rate supports efficient processing of wideband signals.
• Low power consumption design enables extended operation in battery-powered devices while maintaining stable electrical characteristics.

Applications

• Portable medical instrumentation requiring precise signal amplification under limited power constraints
• Active filtering circuits in audio and communication systems needing high slew rates
• Data acquisition systems utilizing analog front-end conditioning for sensor signals

Procurement Notes

Verify the manufacturer origin as Elantec Semiconductor, noting that the company has undergone acquisitions which may affect current production status. Confirm the specific suffix 'ISZ' corresponds to the industrial temperature grade and SOIC-8 package variant. Request the official datasheet to validate pinout compatibility and electrical limits before finalizing procurement orders.

Selection Notes

Select this component when a rail-to-rail output is required alongside moderate bandwidth and low power consumption. Compare against similar op-amps if higher precision or lower noise is necessary, as this model prioritizes speed and efficiency over ultra-low offset voltage. Ensure the operating environment falls within the specified industrial temperature range for reliable performance.

Part Context

The EL1517BISZ belongs to the EL1517 series of high-speed operational amplifiers designed for versatile analog signal processing tasks. This series is characterized by its CMOS technology, which balances performance metrics like slew rate and bandwidth with low static power draw. The part serves as a general-purpose solution for applications transitioning from traditional bipolar op-amps to more energy-efficient CMOS architectures.

Replacement Considerations

Check for direct replacements such as the EL1517CN or other variants within the same family that may differ only in temperature rating or packaging. Verify pin-for-pin compatibility with alternative manufacturers' parts offering similar 10MHz bandwidth and rail-to-rail output specifications.
