STEVAL-CCA011V1
Description
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 short-
circuit protection and thermal shutdown protection
and it is available in a 16-bumps Flip-Chip
package.
