TDA8944J2 x 7 W stereo Bridge Tied Load (BTL) audio amplifierRev. 02 — 14 February 2000 Product specificationcc1. General descriptionThe TDA8944J is a dual-channel audio power amplifier with an output power of2 × 7 W at an 8 Ω load and a 12 V supply. The circuit contains two Bridge Tied Load(BTL) amplifiers with an all-NPN output stage and standby/mute logic. The TDA8944Jcomes in a 17-pin DIL-bent-SIL (DBS) power package. The TDA8944J isprinted-circuit board (PCB) compatible with all other types in the TDA894x family.One PCB footprint accommodates both the mono and the stereo products.2. Features Few external components Fixed gain Standby and mute mode No on/off switching plops Low standby current High supply voltage ripple rejection Outputs short-circuit protected to ground, supply and across the load Thermally protected Printed-circuit board compatible.3. Applications Mains fed applications (e.g. TV sound) PC audio Portable audio.4.
