STEVAL-CCA011V1: 2.5W x 2, 2.5 ~ 5.5Vin

Summary

This demonstration board is based on TS2012FC that is a fully differential Class-D stereo power amplifier able to drive up to 1.15 W into an 8 Ω load (1.85 W @ 4 Ω) at 5 V per channel with 1% THD+N max.

The device has four different gain settings that use two digital pins: G0 and G1. Pop and click reduction circuitry provides low on/off switch noise while allowing the device to start within 8 ms.

Two standby pins (active low) allow each channel to be switched off independently.

The TS2012FC also integrates output short circuit protection and thermal shutdown protection
