Product details

Overview

TDA7560H from STMicroelectronics is a quad-channel Class AB audio power amplifier in Flexiwatt25 (horizontal) 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 0.35 A high-side driver, and supports automute on low supply voltage detection.

For engineers reviewing the TDA7560H datasheet, TDA7560H pinout, TDA7560H application, or TDA7560H equivalent, key selection criteria include 2 Ω load capability, rail-to-rail complementary P/N-channel output stage, fixed 26 dB gain, DC offset detection on Pin 25, and thermal limiter with soft-clamp behavior under overtemperature.

Technical Context

The TDA7560H implements a fully complementary bipolar/CMOS/DMOS (BCD) process output stage enabling rail-to-rail voltage swing and minimized saturation losses. Its four independent amplifier channels share a common thermal substrate and integrate dedicated protection circuitry including output short-circuit detection to GND, VS, and across loads.

It embeds an internal DC offset detector (enabled via MUTE pin) that monitors differential output voltage and asserts fault on HSD pin when exceeding ±4 V; standby and mute functions are CMOS-compatible with defined threshold voltages (V_ST-BY = 1.5 V OFF / 3.5 V ON; V_MUTE = 1.5 V MUTE / 3.5 V PLAY).

Key Specifications

Parameter	Value and Actual Design Meaning
Output Power (4 Ω)	4 × 51 W max @ 14.4 V, 1 kHz, 10 % THD - enables full-range speaker drive without external boost stages
Output Power (2 Ω)	4 × 80 W max @ 14.4 V, 1 kHz, 10 % THD - supports high-current subwoofer and low-impedance coaxial configurations
THD+N	0.006 % typ. @ 4 W, 4 Ω - meets Hi-Fi distortion requirements for front-stage amplification
Voltage Gain	26 dB fixed (typ.) - eliminates need for external gain-setting resistors or compensation networks
Supply Voltage Range	13.2–15.2 V operating; 28 V DC absolute max - compatible with automotive battery transients and alternator ripple
Thermal Resistance (j-case)	1 °C/W max - mandates heatsink with ≤2 °C/W thermal resistance for continuous 4 × 30 W operation at 70 °C ambient
Input Impedance	100 kΩ typ. - ensures compatibility with standard preamp outputs without loading effects
Standby Current	≤20 µA @ V_ST-BY = 1.5 V - enables ultra-low-power sleep mode in infotainment head units

Pinout & Package

Package: Flexiwatt25 (horizontal), 25-pin single-in-line (SIL) with integrated heatsink tab. Mounting orientation allows horizontal PCB layout with heatsink attachment to top surface.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 3, 4	Channel 1–4 Non-inverting Inputs	Differential-capable inputs accepting ±8 Vpk signals; no external bias required
5, 9, 13, 17	Channel 1–4 Inverting Inputs	Ground-referenced feedback nodes; enable bridged or single-ended configuration
6, 10, 14, 18	Channel 1–4 Outputs	Complementary P/N DMOS outputs capable of 2 Ω continuous drive with soft thermal limiting
21	ST-BY	CMOS-compatible standby control: <1.5 V = OFF (quiescent current ≤20 µA); >3.5 V = ON
22	MUTE	CMOS-compatible mute control: <1.5 V = muted (≥80 dB attenuation); >3.5 V = active
25	HSD (High-Side Driver Output)	Open-drain fault indicator for DC offset detection; requires 10 kΩ pulldown to GND
23, 24	V_S, GND	Main power supply and ground return; high-current paths routed to heatsink tab

Key Features

Feature	Design Value
Multipower BCD Technology	Enables monolithic integration of bipolar input stage, CMOS logic, and DMOS output transistors - achieving high efficiency and low distortion in one die
On-board 0.35 A High-Side Driver	Drives external MOSFETs for remote speaker switching or zone control without auxiliary drivers
Automute at Min. Supply Voltage	Triggers mute when V_S drops below 7.0 V (typ.), preventing pop noise during engine cranking or brownout
DC Offset Detection	Monitors output differential voltage; asserts HSD pin if \|V_OUT+ − V_OUT−\| > ±4 V - protects speakers from thermal damage due to DC bias
No External Compensation Required	Internally compensated for unity-gain stability with 4–8 Ω loads - eliminates risk of oscillation from layout parasitics

Applications

Use Scenario: Integrated 4-channel amplifier in OEM or premium aftermarket head unit driving front/rear speakers.

IC Role / Device Role / Timing Role: Primary audio power stage delivering full-bandwidth analog output with <0.01 % THD+N at rated power.

Use Value: Eliminates need for external gain-setting components and bootstrap capacitors, reducing BOM count by ≥7 passive parts per channel.

Use Scenario: Compact 4×50 W amplifier module in space-constrained aftermarket enclosures.

IC Role / Device Role / Timing Role: Quad bridge amplifier with shared thermal management and coordinated mute/standby sequencing.

Use Value: Enables 2 Ω stable operation without external current-sense circuitry - supports dual-voice-coil subwoofers directly.

Use Value: On-chip high-side driver (Pin 25) controls external relay or MOSFET per zone - avoids discrete level-shifting circuits.

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 and package; improved ESD rating (±8 kV HBM), lower quiescent current (120 mA typ. vs. 200 mA), identical power specs	Preferred for new designs requiring higher robustness in assembly or harsher EMC environments	Select TDA7561 when long-term field reliability under repeated ESD stress is critical; drop-in replacement otherwise
TDA7388	4 × 41 W/4 Ω max; uses older BCD process; lacks HSD pin and automute; requires external bootstrap caps	Suitable only for cost-sensitive entry-level radios where 2 Ω drive and DC protection are not required	Choose TDA7388 only if legacy design reuse is mandatory and thermal derating to 30 W/channel is acceptable

Compared with TDA7561, the TDA7560H offers identical functionality but slightly higher quiescent current and lower ESD immunity - making it suitable for mature platforms where qualification is complete. Versus TDA7388, it delivers +25 % peak power, integrated protections, and zero-external-compensation operation - justifying its use in mid-to-high-tier automotive audio.

FAQ

What is the minimum recommended heatsink thermal resistance for continuous 4 × 30 W operation?

For continuous 4 × 30 W output into 4 Ω loads at 70 °C ambient, the datasheet specifies a maximum junction temperature of 150 °C and junction-to-case thermal resistance of 1 °C/W. With simulated music-program dissipation of 26 W under worst-case clipping, a heatsink with ≤2 °C/W thermal resistance is required to avoid thermal shutdown.

Can the TDA7560H drive 1 Ω loads?

No - the device is characterized and protected for stable operation down to 2 Ω loads only. Driving 1 Ω loads exceeds absolute maximum output current ratings (10 A non-repetitive, 9 A repetitive) and risks triggering overcurrent protection or thermal shutdown. The datasheet explicitly specifies 2 Ω as the minimum rated load impedance.

How does the DC offset detection function interact with the mute pin?

The DC offset detector activates only when the amplifier is unmuted (MUTE pin >3.5 V) and no input signal is present. If differential output voltage exceeds ±4 V, the open-drain HSD pin pulls low. This behavior is disabled when MUTE is asserted (<1.5 V), ensuring fault detection occurs only during active playback conditions.

Is the TDA7560H pin-compatible with the TDA7560 (vertical package)?

Yes - both share identical pin numbering, electrical functionality, and footprint pad layout. The only difference is mechanical orientation: TDA7560 uses vertical Flexiwatt25 (leads perpendicular to body), while TDA7560H uses horizontal Flexiwatt25 (leads parallel to body). PCB land patterns differ, but schematic symbol and net connectivity are fully interchangeable.
