Figure 35 Temperature Compensation Circuit Example
Example of Using Internal Operational Amplifier when Driving Large Size of LCD
The driving current of the internal operational amplifier in the HD66727 is reduced to control the
consumption current. When load current is apparently large such as when driving large size of LCD panel,
insert a capacitor between V1OUT–V5OUT outputs and V
CC
power supply, and stabilize the output level of
the operational amplifier. Especially the capacitors for V1OUT and V4OUT must be inserted when 1/26
duty or 1/34 duty drives.
