Low voltage audio power stereo amplifier based on TS4984IQT
  • active Active

This evaluation board is designed for the TS4984 stereo audio power amplifier. The micro-package QFN16 (quad, flat, non-leaded, 16-pin) combines space-saving with good thermal dissipation. The BTL gain is set at 2 V for both channels and can be adapted if necessary with a modification of R1/ R8 or R2/R6 values for the left/right channels. The R3/R6 and C3/C5 component locations are empty on the board to allow changes to both input configurations from single-ended to differential.

For use in differential mode, R4/R7 must be modified. The C1/C6 component locations are also left empty so that, if required, a low-pass filter can be added.
