General Description

The MAX8069 is a 1.2V temperature-compensated volt-

age reference. It uses the bandgap principle to achieve

excellent stability and low noise at reverse currents down

to 60µA. The MAX8069 also features excellent stability,

freedom from oscillation. The MAX8069 is a functional

alternative to Maxim’s ICL8069 with an identical pinout.
