High-Performance 12V 20W Stereo Amplifier

Amplifiers which run from 12V DC generally don`t put out much power and they are usually not hifi as well. But this little stereo amplifier ticks the power and low distortion boxes. With a 14. 4V supply, it will deliver 20 watts per channel into 4-ohm loads at clipping while harmonic distortion at lower power levels is typically less than 0. 03%.  visit page. via next.gr

Derived Center-Channel Stereo System

A simple method of deriving a center or third channel without the use of an extra transformer or amplifier, (a) 4- speakers are connected to 8- amplifier taps. 8 and 16- speakers connect to 16- taps, (b) By blending the inputs it is possible to cancel out undesired crosstalk.

2-W Stereo Audio Power Amplifier

DESCRIPTION: The EUA5202 is a stereo audio power amplifier that delivering 2W of continuous RMS power per channel  into 3-Ω loads. When driving 1W into 8-Ω speakers, the  EUA5202 has less than 0.04% THD+N across its  specified frequency range. Included within this device is  integrated de-pop circuitry that virtually eliminates  transients that cause noise in the speakers.  Amplifier gain is externally configured by means of two  resistors per input channel and does not require external  compensation for settings of 2 to 20 in BTL mode (1 to  10 in SE mode). An internal input MUX allows two sets  of stereo inputs to the amplifier. In notebook  applications, where internal speakers are driven as BTL  and the line (often headphone drive) outputs are required  to be SE, the EUA5202 automatically switches into SE  mode when the SE/BTL inputs is activated. Consume  only 7mA of supply current during normal operation,  and the EUA5202 also features a shutdown function for  power sensitive appl…

Improvements to previous generation devices include: lower supply current, lower noise floor, better efficiency, four different gain settings, smaller packaging, and fewer external components. The most significant advancement with this device is its modulation scheme that allows the amplifier to operate without the output filter. Eliminating the output filter saves the user approximately 30% in system cost and 75% in PCB area. The TPA2000D2 is a monoli…
