APPLICATION NOTE
1. For stable operation;
a) To prevent a dependence of “X-Point” on the supply voltage VS,
Case 1 : VB2 is open
VB2 is biased at about 0.76 x VS (-3.95V@VS=-5.2V) by the internal circuit.
Control VB1, so that the voltage difference “VB1–VB2” is constant.
Case 2 : VB2 is biased
Bias VB2 by using the external voltage source independent of VS.
