MAX98357AETE+T

MAX98357AETE+T is the Analog Devices MAX98357A I2S digital-input Class D amplifier in the 16-pin TQFN package, tape and reel — for adding speaker output to ESP32-class, single-board-computer and voice-enabled IoT products: 2.5 V to 5.5 V single supply, 3.2 W into 4 ohms, no MCLK required, 8 kHz to 96 kHz sample rates and filterless outputs needing only one bypass capacitor. Specifying the full ETE+T code is the selection point: it locks the 3 x 3 mm TQFN package rather than the 9-bump WLP variant, in production tape-and-reel packing. Selection advice: the A variant accepts standard I2S data — choose the MAX98357B instead if your host outputs left-justified audio; five pin-selectable gain settings (3 to 15 dB) and left/right/mono-mix channel selection suit single-speaker designs without I2C configuration. Parameters verified against the Analog Devices official product page, which lists the family in production.
