MAX98357AETE+ Amplifier IC 1-Channel (Mono) Class D
The MAX98357AETE+ is a tiny, low-cost, PCM input Class D audio power amplifier from Maxim Integrated (now part of Analog Devices), delivering up to 3.2 W into a 4 Ω load from a single 2.5 V to 5.5 V supply. It integrates a high-efficiency filterless Class D output stage, digital audio interface, and gain control in a compact 16-pin TQFN (3 mm × 3 mm) package, with an operating temperature range of −40 °C to +85 °C. The chip supports sample rates from 8 kHz to 96 kHz and accepts I²S, left-justified, and 8-channel TDM digital audio formats, making it ideal for space- and power-constrained audio applications.
