EUTECH EUA2310 TSSOP-28 带扬声器保护的15-W立体声D类音频功率放大器
DESCRIPTION
The EUA2310 is a high efficiency, 2 channel bridged-tied load (BTL), class-D audio power amplifier. Operating from a 16V power supply, EUA2310 is capable of delivering 15W/ channel of continuous output power to a 8 load with 10% THD+N. The EUA2310 features a differential input architecture offering improved noise immunity over a single-ended (SE) input amplifier. Amplifier gain is internally configured and can be selected to 20, 26, 32 or 36dB utilizing the G0 and G1 gain select pins. Advanced EMI suppression technology enables the use of inexpensive ferrite bead at the outputs while meeting EMC requirements.
The speaker protection circuitry is integrated into EUA2310 to limit the amount of current through the speaker. Meanwhile, the AGC detects output signal clip due to the over level input signal and suppresses it automatically. The Audio Power Amplifier also features short-circuit and thermal protection preventing the device from being damaged during a fault condition. The Audio Power Amplifier is available in thermally efficient 28-pin TSSOP package.
