TDA8579T/N1SJ

Drivers, Receivers, Transceivers Overview

The TDA8579T is a dual-channel differential line receiver designed for audio applications requiring high common-mode rejection. It features a fixed voltage gain of 0 dB and operates within a supply voltage range of 5.0 V to 18 V. The device provides low noise output, typically 3.7 µV, and maintains a total harmonic distortion below 0.1% at 20 Hz to 20 kHz. It includes fast DC settling capabilities with a typical time of 0.2 seconds and offers protection against electrostatic discharge on all pins. The component is housed in an 8-pin Small Outline (SO) package.

Drivers, Receivers, Transceivers Feature Summary

• Eliminates ground noise through excellent common-mode rejection up to high frequencies
• Maintains constant common-mode rejection independent of source resistance
• Includes quick-charge circuitry for rapid DC input voltage settling
• Provides AC and DC short-circuit safety to both ground and supply voltage

Drivers, Receivers, Transceivers Applications

• Car radio systems requiring long connections between signal sources and amplifiers
• Audio applications needing high-level common-mode rejection for line inputs
• Systems where ground noise elimination is critical

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel configuration. Confirm current product status as availability may vary. Ensure compatibility with existing PCB footprints for the SO8 package. Check for any recent revision updates that might affect design-in parameters.

Drivers, Receivers, Transceivers Selection Notes

Select this component when zero gain buffering with superior noise immunity is required. Consider the high input impedance and the need for external coupling capacitors for frequency response control. Evaluate the thermal resistance characteristics if operating near ambient temperature limits.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TDA85xx series of audio interface components from NXP Semiconductors. It serves as a specialized line receiver rather than a power amplifier, focusing on signal integrity preservation over long cable runs in automotive environments.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same family. Verify that substitute parts maintain the 0 dB gain specification and similar CMRR performance metrics.
