Description

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.
