400W Subwoofer amplifier circuit

Features Class-T architecture with proprietary DPP “Audiophile” Sound Quality Full Audio Bandwidth, 20Hz to 20kHz High Efficiency Supports wide range of output power levels and output loads by changing supply voltage and external Mosfets Compatible with unregulated power supplies Output over-current protection Over- and under-voltage protection Over-temperature protection 48-Pin LQFP Package Description The TDA1400 is a one-channel, Amplifier Driver that uses Tripath’s proprietary Digital Power Processing (DPPTM) technology. The TDA1400 offers higher integration over previous Tripath amplifiers driver chipsets while providing exceptional audio performance for real world applications. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers. The TDA1400 is typically configured as a single supply, bridged output. This makes the power supply requirements simpler and maximizes the output power for a giv

Car Subwoofer Amplifier 22 Watt

Circuit Description The stereo signals coming from the line outputs of the car radio amplifier are mixed at the input and, after the Level Control, the signal enters the buffer IC1A and can be phase reversed by means of SW1. This control can be useful to allow the subwoofer to be in phase with the loudspeakers of the existing car radio. Then, a 12dB/octave variable frequency Car Subwoofer Amplifier Low Pass filter built around IC1B, Q1 and related components follows, allowing to adjust precisely the low pass frequency from 70 to 150Hz. Q2, R17 and C9 form a simple dc voltage stabilizer for the input and filter circuitry, useful to avoid positive rail interaction from the power amplifier to low level sections. This unit is intended to be connected to an existing car stereo amplifier, adding the often required extra "punch" to the music by driving a subwoofer. As very low frequencies are omnidirectional, a single amplifier is necessary to drive this dedicated

TDA2030 Audio Amplifier Circuit

Circuit description: Connecting two TDA2030 thru cheap power transistors we can create a amplifier wich can deliver a higher power. With the components value from the schematic the total amplifier gain is 32 dB. The speaker can be 2 ohm instead of 4 ohm if we use the TIP transistors. TDA 2030 is produced by SGS Ates and is a complete audio amplifier. AB class of the final amplifier cand deliver up to 14W on 4 ohm at a +-14V power supply. With a proper designed power supply this audio amplifier can output 200W.
