20-W Stereo Class-D Audio Power Amplifier DESCRIPTION The EUA2123 is a high efficient Class-D audio power amplifier for delivering up to 2 × 20W into a 4Ω stereo mode with a single-ended (SE) configuration or 1 × 40W into an 8Ω mono mode with a bridge-tied-load (BTL) configuration. The high efficiency of the EUA2123 eliminates the need for an external heat sink when playing music. The gain of the amplifier is controlled by two gain select pins. The gain selections are 20, 26, 32, 36 dB. Short circuit and thermal-overload protection prevent the device from being damaged during a fault condition.
