The is a one channel audio power amplifier for an output power 1 W with an 8 load 5 V supply. The circuit contains a BTL amplifier with a complementary PNP-NPN output stage and standby/mute logic. The TDA8541T comes an 8 pin SO package and the an 8 pin DIP package.

ORDERING INFORMATION TYPE NUMBER TDA8541T TDA8541 PACKAGE NAME SO8 DIP8 DESCRIPTION plastic small outline package; 8 leads; body width 3.9 mm plastic dual in-line package; 8 leads (300 mil) VERSION SOT96-1 SOT97-1

DESCRIPTION operating mode select (standby, mute, operating) half supply voltage, decoupling ripple rejection positive input negative input negative loudspeaker terminal supply voltage ground positive loudspeaker terminal

FUNCTIONAL DESCRIPTION The is a BTL audio power amplifier capable of delivering 1 W output power an 8 load at THD = 10% using 5 V power supply. Using the MODE pin the device can be switched to standby and mute condition. The device is protected by an internal thermal shutdown protection mechanism. The gain can be set within a range from dB by external feedback resistors. Power amplifier The power amplifier is a Bridge Tied Load (BTL) amplifier with a complementary PNP-NPN output stage. The voltage loss on the positive supply line is the saturation voltage of a PNP power transistor, on the negative side the saturation voltage of an NPN power transistor. The total voltage loss <1 V and with 5 V supply voltage and an 8 loudspeaker an output power 1 W can be delivered.

Mode select pin The device is in standby mode (with a very low current consumption) if the voltage at the MODE pin is >(VCC - 0.5 V), or if this pin is floating. At a MODE voltage level of less than 0.5 V the amplifier is fully operational. In the range between 1.5 V and VCC 1.5 V the amplifier is in mute condition. The mute condition is useful to suppress plop noise at the output, caused by charging of the input capacitor.
