Description: The EUA2123 is a highly efficient Class-D audio power amplifier capable of delivering up to 20W into a 4-ohm load in stereo mode using a single-ended (SE) configuration, or up to 40W into an 8-ohm load in mono mode with a bridge-tied-load (BTL) configuration. Its high efficiency eliminates the necessity for an external heat sink during music playback. The amplifier's gain can be adjusted through two gain select pins, offering options of 20, 26, 32, and 36 dB. Additionally, the device is equipped with short circuit and thermal overload protection to safeguard against damage in fault conditions. By Eutech Microelectronics Inc.
The EUA2123 Class-D audio power amplifier is designed to provide high-quality audio amplification with a focus on efficiency and reliability. The amplifier operates in two configurations: stereo mode and mono mode, allowing flexibility in various audio applications. In stereo mode, it can drive speakers with a nominal impedance of 4 ohms, providing a substantial output power of up to 20W, which is suitable for driving small to medium-sized speakers in consumer audio applications. In mono mode, the EUA2123 can deliver up to 40W into an 8-ohm load, making it ideal for subwoofer applications or other scenarios where higher power output is required.
The efficiency of the EUA2123 is a critical feature, as it minimizes heat generation during operation. This characteristic allows the amplifier to function without the need for bulky heat sinks, thereby reducing the overall size and weight of the audio system. The design of the amplifier ensures that it can operate effectively in various environments, maintaining performance without the risk of overheating.
The gain control feature, managed through two dedicated pins, provides versatility in audio output levels. By selecting from four different gain settings—20, 26, 32, and 36 dB—designers can tailor the amplifier's performance to match the specific requirements of the audio system, ensuring optimal sound quality and volume levels.
Safety features are integral to the EUA2123's design, with built-in short circuit protection and thermal overload protection. These mechanisms are crucial for preventing damage to the amplifier during fault conditions, enhancing the reliability and longevity of the device in various applications. The EUA2123 is suitable for a wide range of audio applications, including home audio systems, portable speakers, and automotive audio systems, making it a versatile choice for audio engineers and designers.The EUA2123 is a high efficient Class-D Audio power Amplifier for delivering up to 2G—20W into a 4 stereo mode with a single-ended (SE) configuration or 1G—40W into an 8 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 A mplifier is controlled by two gain select pins.
