Description

l
o
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
