Caution
If the absolute maximum rating of even one of the above parameters is exceeded even
momentarily, the quality of the product may be degraded. Absolute maximum ratings, therefore,
specify the values exceeding which the product may be physically damaged. Be sure to use the
product within the range of the absolute maximum ratings.

Note
When to use external LCD driving, this parameter is recommended.
Remarks1.
When to use external LCD driving, keep VSS
< VLC5 < VLC4 < VLC3 < VLC2 < VLC1 ≤ VLCD
2.
When power on or power off moment, keep VDD
≤ VLCD
3.
When to use internal LCD driving circuit and not to use D/A converter, keep voltage inputted to
AMPIN(+) pin to 1.0V to VDD.
