Setting the VCOM
Adjustment Range (R
SET
)
The external resistive voltage-divider sets the maximum
value of the VCOM adjustment range. R
SET
sets the
full-scale sink current, I
OUT
, which determines the mini-
mum value of the VCOM adjustment range. Large R
SET
values increase resolution but decrease the VCOM
adjustment range. Calculate R1, R2, and R
SET
using
the following procedure:
1) Choose the maximum VCOM level (V
MAX
), the mini-
mum VCOM level (V
MIN
), and the AVDD supply
voltage (V
AVDD
).
2) Calculate the R1 / R2 ratio:
3) Calculate the R1 / R
SET
ratio:
4) Choose R
SET
according to the limits shown in the
Electrical Characteristics
section and calculate the
values for R1 and R2.
5) The resulting resolution is:
A complete design example is given below:
1) V
MAX
= 5V, V
MIN
= 3V, V
AVDD
= 10V
4) If R
SET
= 24.9k
, then R1 = 200k
and R2 =
200k
5) Resolution = 15.75mV
