MAX1681是美国MAXIM公司的新产品,工作频率为1MHz。与一般工作频率为10kHz或几十kHz的同类器件相比,其外接电容容量可选得很小,并且有较低的输出电阻。该器件工作电压为2.0～5.5V,输出-2.0～-5.5V(也可接成倍压电路),最大输出电流可达125mA。由于振荡频率达1MHz,仅用两个1μF的外接电容即可(一般需10～150μF)。由于采用SO-8封装,若
MAX1681 MAXIM company is the United States new products, operating frequency of 1MHz. With the general operating frequency of 10kHz or tens of kHz compared to similar devices, the external capacitor capacity can be selected very small, and have a lower output resistance. The device operating voltage of 2.0 ~ 5.5V, output -2.0 ~ -5.5V (also can be accessed as double voltage circuit), the maximum output current up to 125mA. As the oscillation frequency of 1MHz, only two 1μF external capacitor can be (usually 10 ~ 150μF). As a result of SO-8 package, if
