Function
Reserved
Adjustment of the DAC reference.
Vref = 2V
Vref =2.5V
Vref = 3V
Vref = 3.5V
Function
Divide the reference for the DAC and enable output amplification by 2 of
the To and Ta outputs. Must be set for Vref=3.5V,4V,4.5V.
Enable the DAC regulator
Enable low noise.
Control the gain of the IR amplifier chain (see ‘IR amplifier chain’)
