TDA2005 description: The TDA2005 is a class B dual audio power amplifier in Multiwatt11 package specifically designed for car radio applications. Power booster amplifiers can be easily designed  using this device that provides a high current  capability (up to 3.5 A) and can drive very low  impedance loads (down to 1.6  in stereo  applications) obtaining an output power of more than 20 W (bridge configuration).  TDA2005 Audio Amplifier 2x10w TDA2005 features: High output power: Po = 10 + 10 W @ RL = 2 , THD = 10 % Po = 20 W @ RL = 4 , THD = 10 %. Protection against: Output DC and AC short circuit to ground Overrating chip temperature Load dump voltage surge Fortuitous open ground Very inductive loads Loudspeaker protection during short circuit for one wire to ground TDA2005 circuit diagram: TDA2005 Audio Amplifier 2x10w TDA2005 layout: PCB TDA2005 Audio Amplifier 2x10w Layout TDA2005 Audio Amplifier 2x10w...

Overview The STK400-030 is a 3-channel AF power amplifier IC supporting multichannel speakers. One package includes 20W×3ch for Lch, Rch and Cch. It is pin compatible with both 3-channel output devices (STK400-*00 series) and 2- channel output devices (STK401-*00 series). The output load impedance is 6/3Ω. 20W+20W+20W Amplifier Circuit diagram

Description: The TDA7374B is a new technology class AB Audio Dual Bridge Power Amplifier in Multiwatt package designed for car radio applications. Thanks to the fully complementary PNP/NPN output configuration the high power performances of the TDA7374B are obtained without bootstrap capacitors.

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
