STEVAL-CCA011V1

Filter-free stereo 2x2.5 W Class-D audio power amplifier demonstration board based on the TS2012FC
  • Obsolete

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 at 5 V per channel.

It achieves better efficiency compared to typical Class-AB audio amps.

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 shortcircuit protection and thermal shutdown protection and it is available in a 16-bumps Flip-Chip package.
