TDA8542AT
General description
The TDA8542AT is a two channel audio power amplifier for an output power of 2 x 1.5 W with an 8 W load at a 6 V supply. The circuit contains two Bridge-Tied Load (BTL) amplifiers with a complementary PNP-NPN output stage and standby/mute logic. The TDA8542AT comes in a 20-pin SO package.
Features
- Flexibility in use
- Few external components
- Low saturation voltage of output stage
- Gain can be fixed with external resistors
- Standby mode controlled by CMOS compatible levels
- Low standby current
- No switch-on/switch-off plops
- High supply voltage ripple rejection
- Protected against electrostatic discharge
- Outputs short-circuit safe to ground, VCC and across the load
- Thermally protected.
