This document introduces the use of the SSM2317 evaluation board, which is a highly integrated single-chip mono Class-D audio amplifier that can maximize the performance of mobile phone applications.
The SSM2317-EVALZ is an evaluation board designed for the SSM2317, a fully integrated, single-chip, mono Class-D audio amplifier optimized for mobile phone applications. The board features a complete application circuit capable of driving a loudspeaker with a minimum impedance of 3 Ω from a single 2.5 V to 5.5 V supply.
| Supply Voltage | 2.5 V to 5.5 V |
|---|---|
| Output Power | 3 W |
| Load Impedance | 3 Ω |
| Maximum Peak Current | 0.33 A |
| Minimum Speaker Impedance | 3 Ω |
Remove the jumper across Pin 1 and Pin 2 of J2 to enable the amplifier.
Place a jumper across Pin 3 and Pin 4 of J2 to disable ALC mode.
Remove the EMI filtering (L1/L2 and C6/C7) by shorting across the L1 and L2 terminals.
