Mouser Electronics, Inc., the industry's leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the MAX9838x digital input Class-D amplifiers from Analog Devices / Maxim Integrated.
The Analog Devices / Maxim Integrated MAX9838x digital input Class-D amplifiers feature integrated IV feedback and Brownout Protection in a small 2.93 mm2, 16-pin WLP (0.4 mm pitch) space-saving package. With a wide 2.3 V to 10 V supply voltage range, these amplifiers pair Class-AB level audio performance with the efficiency needed to extend battery life in single-cell, two-cell, and externally regulated/boosted portable applications. The MAX98388 is optimized for up to 5.5 V applications (single-cell), while the MAX98389 is optimized for 5 V to 10 V cases (two-cell).
The device provides a PCM interface for audio playback and IV feedback data and pairs this with a standard I2C interface for device control and status readback. The PCM interface also supports audio data formats such as I2S, left justified, and TDM timing. A unique clocking structure eliminates the need for an external high-frequency reference clock. In addition to reducing device size and pin count, eliminating this clock saves interface power while reducing the risk of EMI from high-speed switching and potential board coupling issues.
Applications for the MAX9838x amplifiers include AR/VR wearables, LRA haptic drives, smartwatches, IoT devices, gaming devices, and notebooks and tablets.
