Eleven W Stereo or 22 W Mono Power Amp . Integrated AF power amps have seen great improvements in recent years offering improved power and easier use. The TDA1519C from Philips contains two power amplifiers providing 11 W per channel stereo or 22 W mono when the two channels are connected in a bridge configuration. The special in-line SIL9P package outline allows the chip to be conveniently bolted to a suitable heatsink. The TDA1519CSP is the SMD version, in this case the heat sink is mounted over, and in contact with, the top surface of the chip.  11W Stereo Amplifier Circuit Diagram The operating voltage of this device is from +6V to +17.5V. The two channels of the amplifier are different in that one channel, between pins 1 and 4, is a non-inverting amplifier, while the other between pins 9 and 6 is an inverting amplifier. It is therefore necessary in stereo operation, to wire the speakers so that one of them has its polarity reversed. Each amplifier has an input impedance of 60kΩ...

This is power amplifier based on IC TDA7294 with output power 150W with 8 ohm impedance, source voltage + - 25V. for circuit see image below. TDA7294 Power Amplifier

Overview: The TB2904H (o) is 4-ch BTL audio amplifier for car audio applications.  This IC can generate higher power: POUT MAX = 43 W as it includes the pure complementary P-ch and N-ch DMOS output stage. It is designed to yield low distortion ratio for 4-ch BTL audio power amplifier, built-in standby function, muting function, and various kinds of protectors.  Circuit Diagram: Circuit diagram for  43 W BTL × 4-ch Audio Power IC Datasheet for TB2904H:  Download

The HA13151/HA13152 are high output and low distortion 4 ch BTL power IC designed for digital car audio. At 13.2 V to 4 W load, this power IC provides output power 14 W with 10% distortion. Circuit Diagram: 14 W 4-Channel Audio Amplifier Datasheet for HA13151: Download
