Output voltage selection
Each LNBH26 channel is provided with 15 output voltage levels (7 levels for 13 V range
when VSEL4-A/B=0 and 8 levels for 18 V range when VSEL4-A/B=1) which can be selected
through the register Data1.
Table 14 shows the output voltage values corresponding to
VSELx bit combinations both for channel A and B. If all VSELx are set to “0” the device is set
in standby mode and the VOUT-A/B is disabled.
TJ from 0 to 85 °C, VI = 12 V.
