Title: 70W υψηλής απόδοσης ενισχυτής Post by: mixos on July 26, 2003, 23:19:10 pm Το ολοκληρωμένο TDA1562 αποτελεί από μόνο του έναν ενισχυτή ισχύος 70W στα 4Ω. Μερικά απο τα χαρακτηριστικά του είναι :
· 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 · 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. GENERAL DESCRIPTION The TDA1562 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 radios and boosters) as well as mains fed applications (e.g. midi/mini audio combinations and TV sound). |
