Enhancing Switching from the V6116

Bias Configuration for Large LCD

Temperature compensation/

Contrast adjustment

C = 1µF

Rx is given by the formula

Rx = 4(24 k

Large LCD example:

display refresh rate = 64 Hz

For a single V6116 mux mode 4 driving of such an LCD,

the voltage follower buffer (opamp) requirement is:

peak current 1.8 mA

steady state current typically 150 µA
