SSM2317-MINI-EVALZ: 1.4 W @ 8 Ω, 2.5 ~ 5.5Vin

Summary

The SSM2317 mini evaluation board is a small form factor board (6.6 mm × 6.6 mm) with a pair of differential audio input terminals (IN+ and IN−), a pair of audio signal output terminals (OUT+ and OUT−), a ground terminal, and a VDD terminal. It is designed for easy integration into the SSM2317 application board.

The SSM2317 is a fully integrated, single-chip, mono Class-D audio amplifier. It is designed to maximize performance for mobile phone applications. The application circuit requires a minimum of external components and operates from a single 2.5 V to 5.5 V supply. It is capable of delivering 1.4 W of con-tinuous output power with less than 1% THD + N, driving an 8 Ω load from a single 5.0 V supply.

The SSM2317 is equipped with a differential mode input port and a high efficiency, full H-bridge at the output that enables direct coupling of the audio power signal to the loudspeaker. The differential mode input stage allows for cancelling of common-mode noise.
