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 VSS, 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

From Eq. 6.1
10 = (1 + ( Rb / Ra ) ) x V

From Eq. 6.2

EV
= (1 – ( (63 - 32) / 200 ) ) x 2.0 = 1.69
[V] ------ (Eq. 6.4)
From requirement 3.
10 / ( Ra + Rb ) = 1 [uA] ------ (Eq. 6.5)
From equations Eq. 6.3, 6.4 and 6.5
Ra = 1.69 [M
], Rb = 8.31 [M
]
Table 15 shows the range of V0 depending on the above requirements.

Voltage Follower Circuits
VLCD voltage (V0) is resistively divided into four voltage levels (V1, V2, V3 and V4), and these output impedance
are converted by the Voltage Follower for increasing drive capability. Table 16 shows the relationship between V1
to V4 level and each duty ratio.
