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…

Stereo 2-W Audio Power Amplifier

1W 2W Audio power IC for notebook PC

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 is1 W × 2-channel: 8 Ω, VCC = 5 V or2 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 the automatic power saving). Operating supply voltage: VCC 3.0 V to 5.5 V/ VCC_SP 3.0 V to 5.5 VCircuit Di…
