Overview
The TDA1519C is a Class-B dual output 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 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 for low current consumption
- Short-circuit safe to ground and positive supply rail
- Thermal protection and reverse polarity safety
- Elimination of switch-on/off plops
Applications
- Stereo audio power amplification
- Bridge-Tied Load (BTL) speaker driving
- Consumer audio equipment
Procurement Notes
Verify the specific package variant required, as the TDA1519C family includes through-hole SIL9P, surface-mount SMS9P, and HSOP20 options. Confirm RoHS compliance status and check for obsolescence notices, as NXP frequently updates product lifecycles. Ensure the selected suffix matches the thermal management needs of the target application.
Selection Notes
Select the TDA1519CTH or TDA1519CTD for applications requiring efficient heat dissipation via PCB copper areas or external heatsinks. Use the TDA1519C or TDA1519CSP for lower power or cost-sensitive designs where thermal resistance is less critical. Verify input impedance requirements match the source signal generator capabilities.
Part Context
This component belongs to the TDA151 series of audio power amplifiers. It is pin-compatible with the TDA1519B and TDA1519CSP variants, allowing for design flexibility across different packaging styles while maintaining identical functional performance.

FAQ
What is the maximum load dump voltage protection?
The device is protected against load dump voltages up to 45 V for a duration of 50 ms.
How does the mute/standby switch function?
The M/SS pin controls the mute and standby modes. A voltage above 8.5 V enables operation, between 3.3 V and 6.4 V activates mute, and below 2 V engages standby mode.
