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.
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.
Applications
■ Mains fed applications (e.g. TV sound)
■ PC audio
■ Portable audio.
