STEVAL-CCA012V1 3 W filter-free class-D audio amplifier demonstration board with 6-12 dB fixed gain select based on the TS2007
The STEVAL-CCA012V1 demonstration board is based on the TS2007FC audio power class-D amplifier, housed in a Flip-Chip package, which is capable of driving up to 1.4 W into an 8 Ω load at 5 V. The device offers improved efficiency compared to typical class-AB audio amplifiers.
The TS2007FC allows switching between two different gains: 6 or 12 dB via a logic signal on the GS pin. Pop and click reduction circuitry provides low on/off switching noise while allowing the device to start within 1 ms. An active low standby function permits lower current consumption (down to 1 μA typ). The TS2007FC also integrates output short-circuit protection and thermal shutdown protection.
The STEVAL-CCA012V demonstration board is constructed on a two-layer PCB with easily accessible connectors, allowing users to change or drive the gain select and standby control pin, and to change the input configuration.
