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.

Note 1: In normal use, the reverse voltage cannot exceed the reference voltage. However, when plugging units into a powered-up
test fixture, an instantaneous voltage equal to the compliance of the test circuit will be seen. This should not exceed 20V.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
