Maxim announces the MAX98357 and MAX98358 digital input Class D audio power amplifiers, enabling designers to achieve compact, efficient, plug-and-play solutions at a cost-effective price. In addition to its small form factor, the device is capable of achieving a 3.2W class AB amplifier with Class D amplifier efficiency, resulting in excellent high fidelity sound for a variety of product applications. In traditional designs, when using analog amplifiers, electronics engineers need to work with digital-to-analog converters (DACs) and add line drivers to the application processor. This increases the overall cost of the speaker output and affects the overall solution size. With the increasing popularity of consumer voice control devices, consumers are increasingly demanding sound quality. Designers need to meet the sound requirements while ensuring the simplicity of design and low power consumption and high efficiency. The MAX98357 Pulse Code Modulation (PCM) and MAX98358 Pulse Density Modulation (PDM) plug-and-play speaker amplifiers take advantage of the flexibility of Maxim's pinout. Compared to a typical analog amplifier solution, the number of components is drastically reduced, thereby greatly reducing the size of the solution. Since most users control volume with digital uplinks, these features allow users to take advantage of Maxim's cost-effective wafer-level package (WLP) without the need for expensive PCB VIAs. For superior sound quality, the device uses a high noise immunity digital input with high jitter tolerance (at least 8dB better than competing solutions). The device also provides excellent electromagnetic interference (EMI) suppression, allowing the use of long-line connected speakers without the need for external filtering. In addition, the device offers the industry's highest Class D efficiency. To simplify the design, the Plug and Play feature requires only one user to connect to the power supply. The MAX98357 and MAX98358 provide both a bit clock (BCLK) and a left and right channel clock (LRCLK), eliminating the need for a master clock (MCLK). These amplifiers automate up to 35 clock configurations and 128 digital audio format configurations, further simplifying the design. Automated configuration eliminates the need for complex I2C programming, and customers no longer need to write basic programs to add an audio function. As more and more applications (such as smart speakers) require multi-directional/multi-channel audio, the demand for the MAX98357 and MAX98358 increases, and both are easily daisy-chained to support speaker array amplifiers (via time division multiplexing) That is, TDM supports up to 8 channels). Main advantage • Excellent sound quality: the highest dynamic range (103.5dB), the industry's best total harmonic distortion (THD) and noise (0.013%), excellent 咔嗒/噼噗 suppression (-66dBV exit and shutdown), Provides a comprehensive 咔嗒/噼噗 抑制 suppression circuit • Cost-effective: WLP packages do not require expensive PCB VIA; most applications require only one external component (bypass capacitor), single-supply operation; competing solutions require at least two external components and internal IVA and two supply voltages • Plug and Play: No programming required, auto-configuring 35 different clocks and 128 digital audio formats with a single power supply • Compact: Small solution size (1.93mm2 WLP); three gains for easy connection • Industry's most efficient Class D amplifier: delivering up to 92% efficiency compared to competing solutions Evaluation • “When evaluating audio devices for my home control project, I have been looking for solutions with the best sound quality and small size,†said MarTIn Winston, editor of NewsTIps BulleTIn. “The MAX98357 digital PCM input Class D audio amplifier is available in minimal space. High quality sound, support for Raspberry Pi or other I2S input sources." • “In addition to the highest efficiency and best sound quality in a Class D amplifier, the flexible pinout of the device allows customers to take full advantage of the size and low cost of the WLP package, which will be a killer for most customers.†Maxim Integrated Mobile Greg Mow, audio solutions business manager, said. Supply and price • The MAX98357 and MAX98358 are priced at $0.87; both devices are available through Maxim's official website and franchisees. • Provides evaluation boards for the MAX98357EVKIT#WLP and MAX98358EVKIT#WLP (also available in TQFN packages) for $59.50 Water Purifier Pressure Sensor Shenzhen Ever-smart Sensor Technology Co., LTD , https://www.fluhandy.com
