TDA1562Q中文资料恩XP数据手册PDF规格书

GENERAL DESCRIPTION

The TDA1562 is a monolithic integrated 70 W/4 Ω 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

• 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.
