Low-Voltage Reference
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.
