Maxim Integrated Products, Inc. unveiled the MAX98396 Class D/G speaker amplifier with the industry’s lowest noise and lowest quiescent power consumption, which is nearly five times lower power than similar amplifiers. The 20V digital input audio power amplifier 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 low 15.5uVrms noise floor is 50-percent lower than the closest competitor, allowing speaker placement in near-silent locations.
The MAX98396 is the newest addition to Maxim Integrated’s portfolio of Class D/G amplifiers, offering the industry’s lowest power, lowest noise and highest thermal efficiency demanded by battery powered Bluetooth and always-on smart speakers. The industry-leading power efficiency allows the speaker to be driven higher and longer before reaching the thermal limit. As well, 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.
