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.
