Maxim

Description

DATASHEET The MAX680/ MAX681 pro- vide both a positive step-up charge pump to develop. +10V from +5V input and an inverting charge pump to generate the -10V output MAX681 / . ICL7652 . / . Figure 1 shows a typical method for developing a bipo- lar reference. The circuit uses a MAX681 voltage dou- bler/inverter charge-pump converter to power an. The circuit uses a MAX681 voltage dou- bler/inverter charge-pump converter to power a. MAX480, creating a positive as well as a negative refer- ence voltage.
