EUA5202 2-W Stereo Audio Power Amplifier with Mute 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.
