Features
Description
This evaluation board is designed with the
TS4994 low power differential audio amplifier. The
micro-package DFN10 (dual flat non-leaded 10
pins) allows space saving and good thermal
dissipation. The differential gain is set at 1 V/V
and can be adapted as necessary through a
modification of the R1 to R4 values.
Equation 1
On the board, you can set the Cn3 and Cn4
jumpers can be set to modify the input
configuration from capacitor coupled to common
mode feedback. In capacitor coupled
configuration, the -3dB cut-off frequency in Hz is:
Equation 2
with R in ohms, C in farads and C1=C2. For more
detailed information about component calculation,
refer to the TS4994 datasheet.
