AmplifierCircuits

Description:      The TDA1011 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4Ω load impedance. The device can deliver up to 6 W into 4Ω at 16 V loaded supply in mains-fed applications. The maximum permissible supply voltage of 24 V makes this circuit very suitable for d.c. and a.c. apparatus, while the very low applicable supply voltage of 3,6 V permits 6 V applications. Special features: single in-line (SIL) construction for easy mounting separated preamplifier and power amplifier high output power thermal protection high input impedance low current drain limited noise behaviour at radio frequencies Reference: Supply voltage range Vp...........................3,6 to 20 V  Repetitive peak output current IORM...........max. 3 A  Operating ambient temperature Tamb ........−25 ...
