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 ...

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 an...

Stereo 2-W Audio Power Amplifier

General Description: The AN12941A is an amplifier IC for stereo  speakers which can output 1 W by 8 Ω or 2 W by 4 Ω.  The AGC circuit is built-in to prevent the resonance  or the vibration by the speaker's energy and the  clipping distortion what is called "broken up sound."  of the speakers.  Also, to reduce power consumption, AN12941A  has a built-in function which automatically detects the  input signal and can automatically enter power save  mode when there is no signal.  Features:  Speaker amplifier is 1 W × 2-channel: 8 Ω, VCC = 5 V or 2 W × 2-channel: 4 Ω, VCC = 5 V  Built-in AGC circuit  Prevention of the resonance or the vibration by  the speaker's energy and the clipping distortion  of the speaker by AGC at excessive input signal  (with AGC on/off switch).  Built-in automatic power saving function  It detects input signals and switches on/off (with  the on/off switch for ...
