The 20V digital input audio power amplifier from Maxim Integrated offers 12.7mW of quiescent power to meet and exceed the industry’s power compliance regulations, which support the always-on feature in portable Bluetooth and smart speakers. The MAX98396’s 15.5microVrms noise floor is 50-percent lower than the closest competitor, Maxim claims.
The MAX98396 is ultrasound-ready with 45kHz of bandwidth and a dedicated data path. This feature, combined with artificial intelligence (AI) software and ultrasound, enables touchless gesture sensing, presence detection and proximity sensing.
“The MAX98396 Class D/G amplifier was designed to meet the needs of next-generation smart and wireless speakers,” said Kevin Ko, business manager of Mobile Audio Solutions at Maxim Integrated, in a statement. “The high-resolution audio-compatible speaker amplifier features ultra-low noise performance, making it well-suited for placement bed side. Upgraded, ultrasound-ready features enable the newest trend of contactless smart speakers.”
The MAX98396 is available at Maxim Integrated’s website for $1.12 in quantities of 1,000 and above; and is also available from authorized distributors. The MAX98396EVSYS evaluation system is available for $184.00.
