All four devices include a high-performance AV DD linear regulator, a positive charge-pump regulator, a negative charge-pump regulator, and built-in power-up sequence control. The MAX8710/MAX8711/MAX8761 also include a high-current operational amplifier. Additionally, the MAX8710/ MAX8761 provide logic-controlled high-voltage switches to control the positive charge-pump output. The linear regulator directly steps down the input voltage to generate the supply voltage for the source-driver ICs (AV DD ). The two built-in charge-pump regulators are used to generat...
