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 Ω 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 frequencies
