MAX98395 Digital Input Class DG Amplifier Analog Devices MAX98395 Digital Input Class DG Amplifier offers industry-leading quiescent power featuring IA/ sense and dynamic headroom tracking (DHT). The MAX98395 precision output current and voltage monitoring (1/V sense) enable speaker protection algorithms to be run by a host device. The spread spectrum modulation (SSM) and edge rate control minimize EMI and eliminate the need for the output filtering found in traditional Class-D devices.
