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

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.
