*1. In DACA-, the reversed voltage of the DACA+ is output. In other words, when DACA+ = +10 V, then DACA-
= -10 V
. In this case, between DACA+ and DACA-, a 20 V potential difference is generated. The same ap-
plies to DACB+/DACB-.

DA Output Method
The following two methods are available for DA output.
•
FilteredPWM
• TrueDAC
This section describes each of the methods.
FilteredPWM
This is a method for creating analog output by smoothing the PWM pulse.
The relationship between the set value and output voltage is shown below
