TDA1519CSP/N3,112

Overview

The TDA1519CSP/N3,112 is a Class-B dual output audio power amplifier manufactured by NXP USA Inc. It operates within a supply voltage range of 6.0 V to 17.5 V and delivers up to 22 W in Bridge-Tied Load (BTL) configuration or 11 W per channel in stereo mode at 4 Ω with 10% THD. The device features a fixed gain of 40 dB, low thermal resistance, and integrated protection against short circuits, thermal overload, and reverse polarity. It utilizes a 9-lead surface-mount single in-line plastic package.

Feature Summary

• Integrated mute and standby switch functionality for low quiescent current consumption
• Capable of handling high energy on outputs even when the supply voltage is zero
• Includes comprehensive protection mechanisms such as load dump, AC/DC short-circuit safety, and thermal shutdown
• Designed for BTL operation requiring minimal external components

Applications

• Bridge-Tied Load (BTL) speaker systems
• Stereo audio amplifier configurations
• Mains-fed consumer electronics applications

Procurement Notes

Verify the specific ordering suffix and package variant against the official NXP product specification before procurement. Confirm that the component status aligns with project requirements, as availability may vary. Ensure design compatibility with the 9-lead SMS9P package dimensions and soldering profiles specified in the datasheet.

Selection Notes

Select this component for applications requiring high output power in a compact surface-mount form factor. Consider the fixed 40 dB gain and differential input stages when designing the signal chain. Evaluate thermal management strategies based on the junction-to-ambient thermal resistance values provided in the specifications.

Part Context

This part belongs to the TDA1519C family of integrated circuits, which includes variants like the TDA1519CTH and TDA1519CTD. These devices are designed as dual output amplifiers offering flexibility in stereo or BTL modes. The family shares identical input characteristics and pin compatibility with earlier versions such as the TDA1519B.

Replacement Considerations

The TDA1519CSP is pin-compatible with the TDA1519B. Designers should verify electrical parameter overlaps if substituting between these specific models.
