Description
The STEVAL-CCA038V1 demonstration board is
designed for the TS4871 low power audio
amplifier. The micro package DFN8 (dual flat non-
leaded 8-pin) 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.
On the board, it is possible to modify the input
configuration from single ended to differential.
More information regarding component
calculations is available in the TS4871 datasheet.
