AU5517DR2

Overview

The AU5517DR2 is a dual operational transconductance amplifier manufactured by onsemi. It features two current-controlled amplifiers with differential inputs and push-pull outputs in a 16-pin SOIC package. The device incorporates linearizing diodes at the inputs to enhance circuit performance, providing a 10 dB signal-to-noise improvement referenced to 0.5% total harmonic distortion. It is designed for programmable gain applications and industrial environments.

Feature Summary

• Contains two current-controlled transconductance amplifiers with differential input and push-pull output architecture
• Integrates linearizing diodes at the inputs to improve signal-to-noise ratio and reduce distortion
• Optimized for significant design advantages in programmable gain applications compared to similar devices

Applications

• Programmable gain applications
• Industrial control systems
• Signal conditioning circuits requiring low distortion

Procurement Notes

Verify the specific suffix DR2 against the manufacturer's official datasheet to confirm pinout compatibility and packaging dimensions. Ensure the component meets RoHS compliance requirements if mandated by your assembly standards. Cross-reference the ordering part number with the latest onsemi documentation to avoid discrepancies between legacy AU5517 variants and current production units.

Selection Notes

Select this component when designing circuits that require precise transconductance control rather than voltage amplification. The integrated linearizing diodes make it suitable for applications demanding high fidelity with minimal external compensation components. Consider the 16-pin SOIC package constraints for PCB layout and thermal management during the initial design phase.

Part Context

The AU5517 belongs to the NE5517 series of dual operational transconductance amplifiers. This family is distinguished from standard voltage-feedback op-amps by its current-output nature, making it ideal for voltage-to-current conversion tasks. The AU5517 variant specifically denotes automotive or enhanced grade specifications within the broader NE5517 product line offered by onsemi.

Replacement Considerations

The NE5517D is a direct functional equivalent within the same series. Verify that the lead-free status and specific electrical tolerances of the replacement match the original design requirements.
