TDA8542AT

The TDA8542AT is a two channel audio power amplifier for an output power of 2 ´ 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.

TDA8542AT has many unqiue features: The first one is few external components.The second one is low saturation voltage of output stage.The third one is gain can be fixed with external resistors.The forth one is standby mode controlled by CMOS compatible levels.The fifth one is low standby current.The sixth one is no switch-on/switch-off plops.The seventh one is high supply voltage ripple rejection.The eighth one is protected against electrostatic discharge.The ninth one is outputs short-circuit safe to ground, VCC and across the load.The tenth one is flexibility in use.There are some limiting values about it.supply voltage(VCC) is -0.3 V min and 18 V max.repetitive peak output current(IORM) is 1 A max.total power dissipation(P(tot)) is 2.2 mA typ.storage temperature(Tstg) is -55°C +150°C.Ambient temperature(Tj) is -40°C to 85°C.
