5. RELATIONSHIP BETWEEN INPUT DATA AND OUTPUT VOLTAGE VALUE
This product incorporates a 6-bit D/A converter whose odd output pins and even output pins output respectively
gray scale voltages of differing polarity with respect to the LCD’s counter electrode (common electrode) voltage. The
D/A converter consists of ladder resistors and switches.
The ladder resistors (r0 to r62) are designed so that the ratio of LCD panel

respectively, input gray scale voltages of the same polarity with respect to the common voltage. When fine-gray scale
voltage precision is not necessary, there is no need to connect a voltage follower circuit to the
