Product details
Overview
TDA7560 from STMicroelectronics is a quad-channel Class AB audio power amplifier in Flexiwatt25 (vertical) package, designed for high-power car radio systems. It delivers up to 4 × 51 W into 4 Ω and 4 × 80 W into 2 Ω at 14.4 V, features MOSFET output stage, integrated high-side driver (0.35 A), and supports automute, standby, and DC offset detection for speaker protection.
For engineers reviewing the TDA7560 datasheet, TDA7560 pinout, TDA7560 application, or TDA7560 equivalent, this page provides verified electrical specs, thermal data, real-world distortion curves, PCB layout guidance, and functional alternatives for automotive audio design validation and BOM optimization.
Technical Context
The TDA7560 uses Multipower BCD technology with fully complementary P-Channel/N-Channel output transistors enabling rail-to-rail voltage swing and minimized saturation losses. Its internal fixed gain of 26 dB eliminates external compensation and bootstrap capacitors.
It integrates a dedicated DC offset detector (enabled via MUTE pin) that monitors differential output voltage and signals fault on HSD pin, requiring only a 10 kΩ pulldown resistor. The on-board 0.35 A high-side driver supports external load switching without auxiliary circuitry.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel automotive audio amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDA7561 | Same pinout, 4 × 45 W/4 Ω EIAJ rating, lower thermal dissipation (65 W max), reduced THD (0.005 % typ.) | Better suited for space-constrained dash units where peak power demand is moderate and thermal margin is tight | Select when prioritizing lower heatsink mass and tighter distortion spec over absolute peak output power |
| TDA7388 | 4 × 41 W/4 Ω, smaller Flexiwatt23 package, no integrated HSD, higher quiescent current (120–400 mA) | Targeted at cost-sensitive entry-level radios; lacks automute and DC offset detection functions | Choose for legacy designs requiring footprint compatibility and simplified protection scheme |
Compared with TDA7560, TDA7561 offers improved distortion and thermal efficiency at slightly lower peak power, while TDA7388 trades protection features and output capability for lower cost and smaller footprint - making TDA7560 optimal for premium-tier car audio demanding both robustness and headroom.

FAQ
What is the minimum recommended SVR capacitor value for pop-free startup?
The datasheet specifies a minimum 10 µF SVR capacitor to simultaneously ensure adequate ripple rejection and controlled turn-on/off timing. This value optimizes transient suppression during power sequencing and prevents audible "pop" noise at amplifier enable/disable transitions, as validated in Figure 3's standard test circuit.
Can the TDA7560 drive 2 Ω loads continuously without thermal shutdown?
Yes - with proper heatsinking. At 4 × 2 Ω operation and Tamb = 70 °C, simulated power dissipation reaches 26 W under worst-case music/speech conditions (Figure 18). Using a heatsink with ≤2 °C/W thermal resistance keeps junction temperature below 150 °C, avoiding thermal limiter activation during sustained use.
How does the DC offset detector function without external components?
The detector activates when MUTE = 8 V and ST-BY = 5 V, monitoring differential output voltage. If offset exceeds ±2 V (typ.), Pin 25 (HSD) pulls low. A 10 kΩ pulldown resistor to GND is mandatory for correct logic-level signaling - no op-amps, comparators, or external biasing are needed.
Is the TDA7560 pin-compatible with earlier ST audio amplifiers like TDA7384?
No - TDA7560 uses Flexiwatt25 (25-pin vertical), whereas TDA7384 uses Flexiwatt23 (23-pin). Pin counts, spacing, thermal pad layout, and functional pin assignments differ. Direct replacement requires PCB redesign; however, TDA7561 shares identical pinout and mechanical footprint for drop-in upgrade paths.
