TDA1560Q/N4C,112

Overview

The TDA1560Q is a mono Bridge-Tied Load (BTL) Class-H high power amplifier designed for automotive applications. It delivers 40 W typical output power into an 8 Ω load at 10% THD, utilizing external lift capacitors to boost internal supply voltage during high-demand signals. Operating parameters include a supply voltage range of 8.0 V to 18.0 V and a fixed voltage gain of 30 dB. The device features low quiescent current of 100 mA typical and standby current of 55 μA maximum. Thermal protection limits output power to 10 W if case temperature exceeds 120 °C.

Feature Summary

• Class-H operation with internal voltage lifting via external capacitors for high peak power
• Integrated thermal protection switching to Class-B mode under excessive heat
• Short-circuit safe to ground, supply rail, and across the load
• Diagnostic facility providing fault indication via dedicated pin

Applications

• Car radio audio amplification
• Automotive infotainment systems
• High-power single-channel speaker driving

Procurement Notes

Verify component authenticity through authorized Philips Semiconductors channels or certified distributors. Confirm package integrity matches DBS17P specifications. Ensure storage conditions adhere to specified limits to prevent moisture damage prior to soldering. Validate ordering suffixes against official documentation for exact lead length and material variations.

Selection Notes

Select this component for designs requiring high efficiency in music signal reproduction where average power dissipation is lower than peak capability. Ensure heatsink design accommodates ambient temperatures up to 50 °C while maintaining case temperature below 120 °C for full Class-H performance. Verify external capacitor values align with desired frequency response characteristics.
