VLCD set

The LCD Voltage VLCD at reference temperature (TA = 25°C) can be set using the Voltage

Range V0R, Electronic Volume EV and VOP registers content according to the following

formula:

VLCD (T=TA) = ( V0P[7:0] + EV[4:0] - 16 + 32 · V0R[2:0]) · B + VLCDMIN

with the following values:

For information on VLCD thermal compensation see PAR. 8.18 .
