speed_control is the D/A converter power control option (0—slow or 1—fast (default)).
Test conditions from TI's data sheet (TLV5618A D/A converter) for the speed-control option:
- No load.
- All inputs are at GND or VDD.
- D/A converter latch = 0x800.
channel is the D/A converter output channel to write (0–3).
rawcount is the data value corresponding to the desired voltage on the analog output channel (0–4095).
RETURN VALUE
None
SEE ALSO
anaOut, anaOutVolts, anaOutCalib
Sets the voltage of a D/A converter output channel.
PARAMETERS
channel is the D/A converter output channel (0–3).
rawcount is a data value corresponding to the voltage desired on the output channel (0–4095).
RETURN VALUE
0 if sucessful.
-1 if rawcount is more than 4095.
SEE ALSO
anaOutDriver, anaOutVolts, anaOutCalib
Sets the voltage of a D/A converter output channel by using the previously set calibration constants to
calculate the correct data values.
PARAMETERS
channel is the D/A converter output channel (0–3).
voltage is the voltage desired on the output channel.
RETURN VALUE
None.
