TDA1519CJ/N3C,112

Overview

The TDA1519C is a dual output Class-B power amplifier designed for stereo or Bridge-Tied Load (BTL) configurations. It delivers up to 22 W in BTL mode or 2 x 11 W in stereo mode at 4 Ω with 10% THD. The device operates on a supply voltage ranging from 6 V to 17.5 V and features a fixed closed-loop gain of 40 dB. Key electrical characteristics include low DC output offset voltage, high ripple rejection, and integrated mute/standby functionality.

Feature Summary

• Integrated mute and standby switch with low quiescent current consumption
• Comprehensive protection against AC/DC short circuits, thermal overload, and reverse polarity
• Capable of handling high energy pulses at outputs during power-off conditions
• Eliminates audible switching noises during power-on and power-off cycles

Applications

• Stereo audio amplification systems
• Bridge-Tied Load (BTL) speaker driving applications
• Consumer electronics requiring high output power with minimal external components

Procurement Notes

Verify the specific package variant required for the design, as the TDA1519C family includes through-hole SIL9P, surface-mount SMS9P, and HSOP20 options. Confirm that the selected part number matches the intended pin configuration and thermal management strategy. Ensure compliance with RoHS directives if applicable to the manufacturing process.

Selection Notes

Select this component for applications requiring robust protection features and high efficiency without complex external biasing networks. The fixed 40 dB gain simplifies circuit design by reducing the need for external feedback resistors. Consider the thermal resistance requirements based on the chosen package and expected ambient operating temperatures to ensure reliable performance within the specified junction temperature limits.

Part Context

This device belongs to the TDA151 series of audio power amplifiers manufactured by NXP Semiconductors. It serves as an upgrade or alternative to previous versions like the TDA1519B, offering enhanced reliability and simplified application circuits. The product specification defines its electrical parameters and mechanical dimensions for integration into various consumer audio hardware designs.

Replacement Considerations

The datasheet explicitly states that the TDA1519C is pin-compatible with the TDA1519B and TDA1519CSP. Designers replacing older units can utilize these variants directly without modifying the printed circuit board layout, provided the functional specifications meet the system requirements.
