The following graph shows the voltage output characteristics of the Analog Out-
put Unit.

Note
1. If the setting pins are set to prohibit negative voltage output, no negative
voltage will be output.
2. In 2’s complement, –1 is FFFF, by subtracting 1 continuously, the smallest
value will be F800.
Current Output
Data between 0000 to 07FF (hexadecimal) for output from the CPU is converted
into a current of 0 to 20 mA and output.
Bits 11 to 14 of the output data have nothing to do with output current (i.e., 0 mA is
output for 0000 and 7800 (hexadecimal)). Bit 15 must be always set to 0. If bit 15
is set to 1, the data conversion of the Analog Output Unit may take longer.
