4.3.12.3 Speaker
DAC channel #0 can be configured as an input to a speaker. A pulse width modulated (PWM) signal goes
through a low-pass filter, changing the high speed digital signal from the Rabbit processor into a smoothly
varying analog signal. This signal is not strong enough to drive the speaker, so it goes through a low volt-
age audio power amplifier before connecting to the speaker line.
filter/amplifier. The output to the speaker is on J6.
A sample WAV files is provided in /Samples/RabbitFlex_BL300F/audio/ or in
/Samples/RabbitFlex_SBC40/audio/ depending on your version of Dynamic C.
RabbitFLEX User’s Manual
NOTE: The operating temperature range for the speaker differs from the operating tempera-
ture range (–40°C to +70°C) of the rest of the RabbitFLEX BL300F components.
