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.

hi toni,
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.
