General description The TDA1562 is a monolithic integrated 70 W/4Ω Bridge-Tied Load (BTL) class-H high efficiency power amplifier in a 17 lead DIL-bent-SIL plastic power package.
The device can be used for car audio systems (e.g. car radios and boosters) as well as mains fed applications (e.g. midi/mini audio combinations and TV sound).
FEATURES of the IC TDA1562 – 70 W high efﬁciency power ampliﬁer
- Very high output power, operating from a single low supply voltage
- Low power dissipation, when used for music signals
- Switches to low output power at too high case temperatures
- Few external components
- Fixed gain
- Differential inputs with high common mode rejection
- Mode select pin (on, mute and standby)
- Status I/O pin (class-H, class-B and fast mute)
- All switching levels with hysteresis
- Diagnostic pin with information about:
- Dynamic Distortion Detector (DDD)
- Any short-circuit at outputs
- Open load detector
- Temperature protection.
- No switch-on or switch-off plops
- Fast mute on supply voltage drops
- Quick start option (e.g. car-telephony/navigation)
- Low (delta) offset voltage at the outputs
- Load dump protection
- Short-circuit safe to ground, supply voltage and acrossthe load
- Low power dissipation in any short-circuit condition
- Protected against electrostatic discharge
- Thermally protected
- Flexible leads.

Hello Tony, thank you for your good site. Please send the PCB sizes to my email. Thank you. Always be successful and up to date, your Iranian friend.
sir..is this good amp?and clear the sound?
can you tell me this car audio are proven and tested??
where can I get the kit to build on my on?
Do you sell it? What does it cost? Shipping to Germany?
Please send me an email.
que software utilizas para tus ´pcb’s
Thanks for your good work please keep it up.
i am your big fan.
can you tell me an other IC which i can use instead of TDA 1562. because it is not available in our area.
WAiting for your good response.
Once Again Thanks in Advance.
Buy in Aliexpress!
hola toni ya no se encuentra disponible el pdf de la placa 1562q
