The TDA1011A 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 device can deliver up to 6 W into 4 Ω 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 5,4 V permits 9 V applications. The power amplifier has an inverted input/output which makes the circuit optimal for applications with active tone control and spatial stereo. 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
