70 W high efficiency power amplifier
with diagnostic facility
with diagnostic facility
The TDA1562Q is a monolithic integrated 70 W/4 W
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,
radio and boosters) as well as mains fed applications
(e.g. midi/mini audio combinations and TV sound).

Features
• 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 across the load
• Low power dissipation in any short-circuit condition
• Protected against electrostatic discharge
• Thermally protected
• Flexible leads.
Operating Temperature Range : – 40° to +85°C
Supply voltage range : 8V to 18V
Package : SOT243-1
