Product Overview

MAX98397EWB+T is a high-efficiency, mono Class-DG speaker amplifier with industry-leading quiescent power, featuring integrated speaker current and voltage sensing (IVSENSE), a brownout-prevention engine (BPE), and dynamic-headroom tracking (DHT). This device also enables ultrasound applications by providing support for sample rates up to 192KHz, a higher passband (for fS > 50KHz), and a bypass path for the ultrasound signals through the amplifier so it is not attenuated by the audio processing. Precision output current monitoring (ISENSE) and voltage monitoring (VSENSE) enable speaker protection algorithms to be run by a host device. Spread-spectrum modulation (SSM) and edge rate control minimize EMI and eliminate the need for the output filtering found in traditional Class-D devices. Applications include mobile speakers and smart speakers, tablets, laptop and desktop computers, soundbars, smart IOT.
  • Wide input supply voltage range from 3V to 28V
  • Total power consumption is 25.3mW typical at (VPVDD= 24V, VVBAT = 5.0V, DG mode)
  • Dynamic range is 117.8dB typical at (ZL = 8 ohm + 33µH, measured using EIAJ method,TA = +25°C)
  • Total harmonic distortion + noise is -85dB typical at (fIN = 1KHz, POUT = 3W, ZL = 8 ohm + 33µH)
  • Peak output power is 100W typical at (ZL = 4 ohm + 33µH; PVDD = 28V; 50Hz (2 period)
  • Efficiency is 83% typical at (VPVDD = 24V, VVBAT = 5.0V, POUT = 1W, ZL = 8 ohm + 33µH, fIN = 1KHz)
  • Class-D EMI reduction enables filter less operation, flexible brownout-prevention engine
  • Spread-spectrum modulation and switching-edge rate control
  • Dynamic headroom tracking (DHT) maintains a consistent listening experience
  • Operating temperature range from -40°C to +85°C, 35-lead WLP package
