Operation

2.1.4

Gain Setting and Input configuration

The gain and input mode settings are programmed via the I

2

C interface. The default gain of the TAS2552

is set to –21.5 dB. The gain can be adjusted by clicking on the orange amplifier block and moving the
slider up/down as illustrated in

. The input can be switched from digital to analog and vice versa

by clicking on the input MUX mode switch.

When clicking on the “Class-D Enable” checkbox, the output of the amplifier will be enabled and the
Class-D will start switching. Set the Volume Control to 0 dB. Refer to the datasheet

for more

details on gain settings.
