TDA8944AJ  
2 x 7 W BTL audio amplifier with DC gain control  
Rev. 01 — 01 March 2002  
Product data  
M3D541  
1. General description  
The TDA8944AJ is a dual-channel audio power amplifier with DC gain control. It has  
an output power of 2 × 7 W at an 8 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 overall gain can be adjusted from +30 dB down to 50 dB using a DC  
control voltage. This feature can be used for volume control or a preset gain.  
The TDA8944AJ comes in a 17-pin DIL-bent-SIL (DBS) power package and is pin  
compatible with the TDA8944J.  
2. Features  
Gain/volume adjustment via a DC control pin  
Soft clipping  
Operating at a low supply voltage  
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 with TDA8946AJ and TDA8580J.  
3. Applications  
Mains fed applications (e.g. TV sound)  
PC audio  
Portable audio.
