Some components may vary according to delivery. WARNING :This product requires the use of a passive radiator of appropriate size. Condition: New Multi-buy: Buy 1 £66.99 each £64.98 each Quantity: 2 available Price: £66. 12 Watt stereo and bridged mono TDA2003 amplifiers The LM3886 is by far the best. printli0 Amplifier Housing,LM3886 All Aluminum Amplifier Chassis DIY Audio Amplifier O6J4 Be the first to write a review. An MKP capacitor of 2,2uF / 400VDClocated at the input to suppress the DC component of the signal. Bluetooth Amplifier Board Class D AMP Module for DIY Wireless Speaker. The filtering of the transistors uses 2 electrolytic capacitors of 63V / 470μF. It’s almost an entire amplifier-on-a-chip, with only a few extra parts required to build a fully functional, high-performance amplifier. With a thermal and electrical stability, the 4145 is equipped with a double protection system sophisticated surge protection (proprietary technology Spike™) and undervoltages, the latter occurring when the power supply drops below 12V. A bit overkill. Originally posted by tc View Post They are 2200uF caps, 22,000uF per rail. Working in Class AB, and capable of 50W continuous power under a load of 8Ω, this trio of transistors can reach 400W peak, with a coherent harmonic distortion rate of only 0.1%. Re: A small DIY LM3886 Chip Amplifier It looks like a lot more, I went with 20,000uF (2x10,000uF) per rail. The amplification module APD87 is based on 3 high-performance circuits LM3886 developed by National SemiConductor.
