TDA1562Q; TDA1562ST;
TDA1562SD
FEATURES
·
Fast mute on supply voltage drops
·
Very high output power, operating from a single low
supply voltage
·
Quick start option (e.g. car-telephony/navigation)
·
Low (delta) offset voltage at the outputs
·
Low power dissipation, when used for music signals
·
Load dump protection
·
Switches to low output power at too high case
temperatures
·
Short-circuit safe to ground, supply voltage and across
the load
·
Few external components
·
Low power dissipation in any short-circuit condition
·
Fixed gain
·
Protected against electrostatic discharge
·
Differential inputs with high common mode rejection
·
Thermally protected
·
Mode select pin (on, mute and standby)
·
Flexible leads.
·
Status I/O pin (class-H, class-B and fast mute)
·
All switching levels with hysteresis
GENERAL DESCRIPTION
·
Diagnostic pin with information about:
– Dynamic Distortion Detector (DDD)
– Any short-circuit at outputs
– Open load detector
– Temperature protection.
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 radios and boosters) as well as mains fed applications
(e.g. midi/mini audio combinations and TV sound).
·
No switch-on or switch-off plops
