INTEGRATED CIRCUITS DATA SHEET TDA1015 1 to 4 W audio power amplifier November 1982 Product specification File under Integrated Circuits, IC01 Philips Semiconductors Product specification 1 to 4 W audio power amplifier TDA1015 The TDA1015 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 4 ? load impedance. The very low applicable supply voltage of 3,6 V permits 6 V applications. Special features are: • 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
