This is a class AB stereo audio power amplifier designed for quality hi-fi applications using a power IC? TDA2005. It is easy to construct and has a minimum of external components. The module has output current protection and thermal protection. This is the data book circuit which produces an excellent sound. The supply voltage required for this kit is 8 – 18V DC at 1 to 2 Amps.
Maximum output power will only be obtained with a power supply of at least 2A at 15V DC, and using 2 ohm speakers (or 2 by 4 ohm speakers in parallel). However approximately 4W per channel can be obtained with only a 15V DC, 1A supply into 4 ohm loads.
The power supply should be well filtered to reduce mains hum, the on board capacitors alone are not adequate for this purpose but are necessary to ensure stability. Extra filtering is unnecessary if operating from a battery.
