4.3.12 Digital-to-Analog Converters
The RabbitFLEX BL300F can have up to two DAC channels. The analog output from channel #0 comes
out on J2, pin 7or can be used to drive the optional speaker output (See
channel #1 comes out on J2, pin 8. There are two voltage output range options:
•
•
There are two things to notice in the circuit schematics for the DAC channels
22). First, the 0-10 V DAC channel uses the op amp to increase the PWM voltage to the desired range.
Second, the +K voltage is user-supplied and must be at least +12 V, and no more than 30 V when either
DAC channel is set to the 0-10 voltage range.

0-3 V
0-10 V
NOTE: The DACs are powered by the same voltage source, which means that a 0-3 V DAC
will be powered by +K on J2 if the 0-10 V DAC also exists. If there is no 0-10 V DAC, any 0-
3 V DACs will be powered by +5 V.
