In Case of Using External Resistors, Ra and Rb. (INTRS = "L")
When INTRS pin is “L”, it is necessary to connect external regulator resistor Ra between VR and V
SS
, and Rb
between V0 and VR.
Example: For the following requirements
1. LCD driver voltage, V0 = 10V
2. 6-bit reference voltage register = (1, 0, 0, 0, 0, 0)
3. Maximum current flowing Ra, Rb = 1 uA
From Eq. 1
Rb
10 = ( 1 +
) x V

From requirement 3.

Ra + Rb
From equations Eq. 3, 4 and 5
Ra = 1.79 [M
]
Rb = 8.21 [M
]
The following table shows the range of V0 depending on the above requirements.
