LKWIC LKP695SS

The LKP695xS series is a programmable voltage reference. It integrates a startup circuit, a bandgap reference with second-order curvature correction, a constant current source, an error amplifier, and overcurrent protection. Connecting an external capacitor of 0.01μF~0.1μF can significantly improve circuit performance. The series offers two accuracy grades (Grade S and Grade T) to meet diverse application requirements. This device is primarily intended to provide a stable voltage reference for high-precision signal acquisition applications; its drive capability is limited, and it is not recommended for use as a device power supply.
