TDA8946AJ
General description
The TDA8946AJ is a dual-channel audio power amplifier with DC gain control. It has an output power of 2x15 W at an 8 Ohm load and an 18 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 for a preset gain. The TDA8946AJ comes in a 17-pin DIL-bent-SIL (DBS) power package and is pin compatible with the TDA8946J.
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 TDA8944AJ and TDA8580J.
