Description
The STEVAL-CCA037V1 demonstration board is
designed to evaluate the TS4990IQT low
power audio amplifier. The micro package DFN8
(dual flat non-leaded 8 pins) allows space saving
and good thermal dissipation.
The BTL gain is set at 2 V/V and can be adapted
if necessary with a modification of two (R1 or R2)
resistor values.
It is possible to modify the input configuration from
single ended to differential of the STEVAL-
CCA037V1 demonstration board.
More information regarding component
calculations is available in the TS4990 datasheet.
