DS

Features: Pin compatible IC series that covers power ratings from 50 W × 2 channels to 180 W × 2 channels at 0.7 or 0.8% THD, 20 Hz to 20 kHz. This allows the use of a common PCB for all output classes.  The pin arrangement is also unified with that of the three-channel STK413-000 series. This means that PCBs designed for three-channel models can also be used for two-channel models.  Miniature package — 50 W/ch to 120 W/ch (THD = 0.8%, f = 20 Hz to 20 kHz): 64 × 36.5× 8.5 mm* — 150 W/ch to 180 W/ch (THD = 0.7%, f = 20 Hz to 20 kHz): 78 × 44× 9 mm* * Not including the IC pins.  Allowable load shorted time: 0.3 s Circuit Diagram: 60W+60W  Audio Power Amplifier

Amplifier circuit is very suitable for use in car audio speakers that use a subwoofer, with a power output of about 60W and impedance of 4 Ohm. Supply voltage ranging from 12V to 35 volts with currents +, -, and ground. If using battery then use 12V DC to DC converter which produces 3 voltage +, -, and ground.
