OUTPUTS
The voltage outputs are generated from PWM pulses, and them filtered result in radiometric tension outputs
(dependent on supply voltage). The two outputs are electrically isolated respect to the logic and each other.
The control of relays is done via VREL1 and VREL2 signals. Also, it needs to be activated the common of both
relays by VCOMREL signal. When the relays are off, the output voltage VO1 and VO2 are the values of
reference voltage VR1 and VR2 connected at each output.
The output values range goes from 0 to 100% of power supplies VPP1 and VPP2 connected to each of the
outputs and have a resolution of 10 bits (1024 values).
