TA8210AH 2 x 22W BTL Car Amplifier Circuit
This is a circuit of 2 x 22 watt BTL amplifier using IC TA8210AH. It is not only an auto amplifier, ideal for a low-frequency auditory approach those hi-fi, with a very good linear feature. Can be fueled by a 12 volt car battery but shi from a 12 volt charger. The chip incorporates four bridge amplifiers available in two by two in order to ensure the output 22 watts per channel on 4 ohms.
TA8210AH - 2 x 22W BTL Car Power Amplifier CircuitNote:
- IC TA8210AH must be connected to a heat sink. A computer cabinet fan can also be used in addition.
- The circuit roughly draws 6A current at 18 V at full volume.So the power supply must be any thing more than 6A.
- Peak supply voltage (0.2s): 50 V
- supply voltage VCC (DC): 25 V
- Operating supply voltage VCC (opr): 18 V
- Output current (peak): 9 A
- Power dissipation PD: 50 W
- Operating temperature: 30~85 °C
- Storage temperature: 55~150 °C

2 X 200W STEREO CLASS T DIGITAL AUDIO AMPLIFIER TDA2075A
GENERAL DESCRIPTION
The TDA2075A is a two-channel, amplifier driver, that uses Tripath’s proprietary Digital Power Processing (DPPTM) technology. The TDA2075A 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 TDA2075A is typically configured as a split-supply, single-ended, stereo amplifier. The TDA2075A can also be configured single-supply, single-ended, stereo amplifier, via external component choice. For applications that require bridged output drive, please refer to the TDA1400.
Applications
- Powered DVD Players
- Mini-Compo Systems
- Audio/Video Amplifiers & Receivers
- Multimedia Speakers
Benefits
- Reduced system cost with smaller/less expensive power supply and heat sink
- Signal fidelity equal to high quality Class-AB amplifiers
- High dynamic range compatible with digital media such as CD and DVD
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

24 W BTL or 2 x 12 W stereo car radio power amplifier
GENERAL DESCRIPTION
The TDA1510AQ is a class-B integrated output amplifier encapsulated in a 13-lead single in-line (SlL) plastic power package. Developed primarily for car radio application, the device can also be used to drive low impedance loads (down to 1,6 Ω). With a supply voltage (VP) of 14,4 V, an output power of 24 W can be delivered into a 4 Ω Bridge Tied Load (BTL), or when used as a stereo amplifier, 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω.
Features
- Flexibility − stereo as well as mono BTL
- Low offset voltage at the output (important for BTL)
- Load dump protection
- A.C. short-circuit-safe to ground
- Low number, small sized external components
- Internal limiting of bandwidth for high frequencies
- High output power
- Large useable gain variation
- Good ripple rejection
- Thermal protection
- Low stand-by current possibility
- High reliability.
