The internal dead time generation block provides accurate gate switch timing and enables tight dead-time settings for better THD performances. In order to maximize other audio performance characteristics, all switching times are designed for immunity from external disturbances such as VCC perturbation and incoming switching noise on the DT pin. Logic inputs are compatible with LST...
