DESCRIPTION
The STABP01 processor is used to control the
BASH® Digital Converter. When used in conjunction
with BASH® amplifiers a fully integrated high efficien-
cy power amplifier is realized.
By analyzing the audio input, the Processor deter-
mines the appropriate on/off events and generates a
digital pulse for the Digital Converter. The converter
turns this pulse into a power signal that feeds the
power amplifier. The feedback system allows the pro-
cessor to constantly adapt to the audio signal and re-
generate the digital pulse thereby maintaining a
constant voltage across the output devices.
