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

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 applications, holding the supply current at 1µA.
FEATURES:
Output Power at 3Ω Load 2W/ch at VDD=5V 800mW/ch at 3V
Low Supply Current and Shutdown Current
Integrated Depop Circuit
Mute and Shutdown Control Function
Thermal Shutdown Protection
Stereo Input MUX
Bridge-Tied Load (BTL) or Single-Ended (SE) Modes.

Description:
The TPA2000D2 is the third generation 5-V class-D amplifier from Texas Instruments. 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 monolithic class-D power IC stereo audio amplifier, using the high switching speed of power MOSFET transistors. These transistors reproduce the analog signal through high-frequency switching of the output stage. The TPA2000D2 is configured as a bridge-tied load (BTL) amplifier capable of delivering greater than 2 W of continuous average power into a 3-Ω load at less than 1% THD+N from a 5-V power supply in the high fidelity range (20 Hz to 20 kHz). With 1 W being delivered to a 4-Ω load at 1 kHz, the typical THD+N is less than 0.08%. A BTL configuration eliminates the need for external coupling capacitors on the output. Low supply current of 8 mA makes the device ideal for battery-powered applications. Protection circuitry increases device reliability: thermal, over-current, and under-voltage shutdown. Efficient class-D modulation enables the TPA2000D2 to operate at full power into 3-Ω loads at an ambient temperature of 85°C.
