Mode 2 for CR#1: GAIN = 12mA(2,400LSB ),OFFSET=4mA (800LSB).
Mode 3 for CR#1: GAIN = 10mA(2,000LSB), OFFSET=0mA (0LSB).
GAIN:
Current output value when digital input value is K2,000. Setting
range is -8 mA ~ +40 mA (-1,600LSB ~+8,000LSB).
OFFSET:
Current output value when digital input is K0. Setting range is
-10 mA ~ +10 mA (-2,000LSB ~+2,000LSB).

The chart above is to adjust D/A conversion characteristic curve for voltage output mode
and current output mode. The conversion characteristic curve can be modified by changing
the OFFSET values (CR#14~CR#15) and GAIN values (CR#18~CR#19) depending on the
application.
Voltage output: 1LSB=10V/4,000=2.5mV.
Current output: 1LSB=20mA/4,000=5 μ A.

Example #1: Adjusting the A/D Conversion Curve in Voltage Input Mode
1. Description:
Example using the ELC-AN06AANN:
•
When CR#1 (b11 ~ b0) is set to voltage input mode (mode 0), the OFFSET value is
set to 0V (K0) and the GAIN value to 5V (K4,000), i.e. input voltage range -10V ~
+10V will correspond to decimal values -2,000 ~ +2,000.
•
When CR#1 (b11 ~ b0) is set to voltage input mode (mode 1), the OFFSET value will
be set to 2V (K400) and the GAIN value to 6V (K1,200), i.e. input voltage -6V ~ +10V
will correspond to values -2,000 ~ +2,000.
2. Addresses Used:
X0=On: Set the input mode of the signals at CH1 as mode 1.
X1=On: Set the OFFSET value of CH1 as 0V (K0) and GAIN value as 2.5V (K500).
M0=On: Disable adjustment on A/D conversion curve
